With the popularity of the Internet, there have been many technologies based on the Internet "cloud" recently. Recently, a user-friendly "sogou Cloud Input Method" was released. So, what exactly is the "cloud input method"? What kind of experience does it bring to users? Compared with the traditional client input method, what are its advantages and disadvantages? Next, let’s explore this "sogou Cloud Input Method" with the author.

　　One,What is "sogou Cloud Input Method"?

　　Sogou Cloud Input Method is a conceptual input method product based on Sogou Pinyin Input Method and cloud computing technology. Compared with the general input method, the most obvious difference is that it relies entirely on operation, has a stronger language model and thesaurus, and can greatly improve the input accuracy, especially the accuracy of long sentences. As a demonstrative concept product, sogou Cloud Input Method can only be used on web pages at present. (Excerpted from sogou Cloud Input Method) official website.

　　Second, the magical installation-free input method

　　Since sogou Cloud Input Method is an installation-free version, all users need to do is add this address to their favorites, which is very convenient and fast, especially on computers without client Pinyin Input Method. If users need to call sogou Cloud Input Method, they only need to directly open "Enable sogou Cloud Input Method" in favorites on the called page, and then they can use sogou Cloud Input Method to input. However, if users open a new page or refresh the page, they need to repeatedly open the "Enable sogou Cloud Input Method" in their favorites to use it.

Figure 2 Add to Favorites (or Click and Play)

Figure 3 Enable sogou Cloud Input Method

　　I thought that sogou Cloud Input Method would use ActiveX technology, which is a common method used by many domestic manufacturers. But as can be seen from the shortcut, sogou Cloud Input Method is based on JavaScript technology. This makes the sogou cloud input method more compatible, and can be widely used in various browsers and operating systems, and it is really easy to use without installation.

　　Third,Input experience

　　The status bar of sogou Cloud Input Method is very simple, and there are only four commonly used function buttons: Chinese-English switching, full/half angle switching, Chinese-English punctuation switching and closing. Sogou cloud input methods all adopt default settings, and users cannot change the input method settings. The functions of fuzzy sound and dynamic word frequency commonly used by users are not integrated.

Figure 4 Status bar of sogou cloud input method

　　Experience: When using sogou Cloud Input Method, the appearance of candidate words is slightly delayed (related to the network speed). But in terms of input accuracy, sogou Cloud Input Method is indeed more accurate than the client version. When the client input method installed by the user conflicts, the sogou Cloud input method automatically switches to the English input method state to avoid the conflict between the two input methods. Users only need to press the shift key to switch between the two input methods freely. The author comments on the input box of Pacific Computer Network, Sina Weibo input box, Discuz! All of them are used well. However, QQ on the web page is inconvenient to use and often cannot be successfully called.

Figure 6 Automatic conflict resolution

　　Fourth, the input measurement

　　As mentioned above, sogou Cloud is indeed more accurate than the client version. Then, I will use a paragraph to test the sogou Cloud Input Method, Input Method 4.3 and Input Method 2.3. All input methods have turned off the functions of fuzzy sound and dynamic word frequency. The author directly inputs the pinyin of a sentence, and then obtains the results of each input method candidate word/sentence.

　　Test three popular keyword input tests

　　From the above tests, we can see that it is indeed much more accurate to input long sentences and popular keywords by using "sogou Cloud Input Method". This should benefit from sogou’s powerful computing and storage server and rich thesaurus, which makes users input easily.

　　Note: Numbers in brackets are the serial numbers of candidate words.

　　Test 4 compatibility test

　　In order to test the compatibility of sogou Cloud Input Method, the author tries to use sogou Cloud Input Method for text input in popular browsers.

Figure 7 is running normally.

Figure 8 is running normally.

　　After testing, sogou Cloud Input Method works well under IE8, Firefox, Opera and Windows. On the contrary, it can’t be called in browser 3 based on IE core, and it works well in Maxthon 2. Sogou cloud input method benefits from JavaScript technology, and the browser has little influence on it. However, the programming language technology adopted by the input editing boxes on the network has become a stumbling block for sogou cloud input method. Although sogou Cloud Input Method is compatible with most input boxes on the Internet, there are still some input boxes that cannot call sogou Cloud Input Method, such as the log editing box in QQ space.

　　Editor’s note:It is reported that Windows of the World browser version 3.0 is temporarily not allowed to run JS directly from favorites due to security mechanism problems, but considering the needs of netizens, a new version will be released soon to solve this problem in a friendly way.

　　summary

　　Sogou Cloud Input Method is an innovative input method in China. With its powerful "cloud computing" technology and rich thesaurus, it provides users with an accurate input tool. Good compatibility, so that users who use various browsers and operating systems can use it.

　　Sogou cloud input method depends on the network, so it can’t be used without the network. Moreover, the response speed of displayed candidate words after input also depends on the user’s network speed, which seriously delays the user’s input speed for users with slow network speed.

　　Because sogou cloud input method can only be used in the edit input box of web pages, the narrow application scope seriously limits the possibility of popularization of sogou cloud input method. After all, at this stage, most users in China use input methods only in tools and tools. Moreover, sogou Cloud Input Method is limited to Pinyin input mode, and does not support Wubi input mode, which also limits the users.

Then, unexpectedly, a clever man woke up from his sleep in an instant. It turned out that becoming a king was just an unrealistic imagination.

In reality, Manggu is an ordinary laundryman in Animal City, doing an ordinary job and living an ordinary life, but he left a deep impression on everyone in Animal City with his positive and funny personality.

By chance, Mungo came to the Royal Palace in Animal City and had a funny conversation with Ms. Fitna, the special adviser of the king. After happily introducing the identity of the laundryman, a funny adventure far beyond Mungo’s expectation was about to burst into laughter in Animal City …

　　Recently, a drink named "Mohji" has exploded in the circle of friends on WeChat, and many Beijingers have lamented that "one sip will make you feel back to childhood". It is understood that the re-listed "Mohji" was launched by the beverage manufacturer Beijing Ershang Mohji Zhonghong Food Co., Ltd. and the e-commerce platform. Beijing Youth Daily reporter found that because of the limited early production of manufacturers, many scalpers started the business of reselling Mohji at a high price on the Internet. The original price was 69 yuan’s box of Mohji peach juice, and the highest price was sold to 150 yuan. In this regard, the person in charge of Mohji, the second merchant, said that it would increase the supply, and hoped that consumers would choose formal channels to buy.

　　Revival of old brand drinks leads to snapping up.

　　Recently, on the e-commerce platform "Daily Fresh", a drink named "Mohji" was labeled as nostalgic by many Beijingers. "Born in 1984, prospered in 1992, and revived in January 2018", even the slogan of the merchant said: "Do you want to have a bite of Mohji in 1992?"

　　The reporter of Beiqing Daily noticed that on this platform, there are two kinds of Mohji peach juice for consumers to choose from, one is 250ml×4 soft-packed Mohji peach juice beverage, which costs 12.9 yuan, and the other is 250ml×24 boxes packed in a whole box, which costs 69 yuan. The person in charge of Daily Youxian told the reporter of Beiqing Daily that Mohji drinks were snapped up by netizens as soon as they were put on the platform.

　　It is reported that Mohji peach juice was popular in the 1990s. Because of its flexible packaging, it is convenient for students to carry it for spring outing and autumn outing, and it occupies a certain share in the beverage market. Together with Arctic Ocean soda and Yili bread, it has become a classic memory of many "post-80s". Mohji not only represents the taste of childhood, but also created many games for children in the era of lack of entertainment facilities. Some netizens said that the correct operation after drinking Mohji is to open the four corners, blow them full and then step on them.

　　However, some netizens commented on the Internet that although the merchants have a nostalgic concept, they feel different from their childhood memories after drinking, and they are disappointed with this newly listed retro drink.

　　There are scalpers selling 150 yuan in a box online.

　　The reporter of Beiqing Daily saw on the daily fresh platform that the whole box of 24 boxes of Mohji peach juice had been sold out, and consumers could only buy it through pre-sale, and the delivery time was around March 10th. At present, consumers can only buy 4 boxes of Mohji peach juice at a price of 12.9 yuan, and each person is limited to one per day.

　　After Mohji’s return to China, the scalpers saw business opportunities. Some scalpers have started the business of increasing the price and reselling on the Internet. The reporter of Beiqing Daily found on a second-hand trading platform that many scalpers are reselling Mohji peach juice at high prices. On this platform, the price of a box of 240ml Mohji peach juice ranges from 5 yuan to 10 yuan, while the price of 24 boxes of original 69 yuan products is increased by scalpers to 80 yuan, 110 yuan and even the most expensive 150 yuan.

　　Subsequently, the reporter of Beiqing Daily consulted a scalper as a buyer. The scalper said that he bought 30 boxes of Mohji at one time on the daily fresh platform, but it was snapped up yesterday when it was hung on the second-hand platform. Now there is no whole box for sale, only 22 boxes are scattered. "This is not something that anyone can grab. I didn’t buy or sell it. There is always a wayward money."

　　These 22 boxes of Mohji peach juice are sold in 10 yuan, and the postage should be paid by the buyer. "Send them directly to the fresh boxes every day and they will arrive next Monday."

　　Another scalper said that a box of Mohji peach juice 5 yuan in his shop can be delivered by flash delivery within the Beijing Fifth Ring Road. The seller said that "there is no starting number, but it is not cost-effective to buy less flash." When the reporter of Beiqing Daily asked about the source of Mohji peach juice in the store and whether it was true or not, the store did not reply.

　　Merchants say that purchases should be made through formal channels.

　　The relevant person in charge of Mohji, the second merchant, told the reporter of Beiqing Daily that Mohji Peach Juice was officially sold on the platform of Daily Youxian on February 5, and it is only sold on this platform at present.

　　According to reports, Mohji Peach Juice was commissioned by Hand-in-Hand Juice Factory, and each machine produced 180,000 boxes a day. Some netizens questioned Mohji’s hype by means of hunger and thirst marketing, and the relevant person in charge said that due to the current hot sales of this beverage, the manufacturer has been speeding up production. "The packaging material manufacturer had already had a holiday, but we asked the packaging material manufacturer to invite the employees back to continue production, and the overtime pay incurred from it was also borne by us." The person in charge of the Second Merchant Mohji said.

　　In response to the high-priced reselling of Mohji on the Internet, the person in charge said that this would never be a manufacturer’s behavior. Although sales have just resumed, it is unlikely that the goods will be counterfeited, but the person in charge still reminds consumers that for the sake of insurance, they should choose formal channels to buy, and manufacturers are also stepping up efforts to ensure supply and meet consumers’ demand for old brands.

1905 movie network news "Long live the movie!"

At 18: 00 French time on June 3, the official film list was announced at the Cannes Film Festival in 2020. Thierry Frémaux, the artistic director, then released a note introducing the overall situation of this year’s film selection.

This year, the global film industry was greatly affected by the epidemic, and the Cannes Film Festival had to be cancelled due to the epidemic.

"Long live the movie! （Viva il cinema！ ) "Fumao takes this classic quote by Italian director Ferini as the conclusion, and sends his best wishes to the present and future of the film.

This year marks the centenary birthday of Ferini and Hou Mai, one of the "Five Tigers of the French New Wave", and the 20th anniversary of Wong Kar-wai’s classic films. Originally, Cannes will hold a series of restoration screening and tribute activities, both online and offline, but now they can’t be seen.

The Cannes Film Festival was originally scheduled to be held from May 12 to 23 this year. After the outbreak of the French epidemic, the film festival was postponed to July, but the French authorities announced that they could not hold large-scale cultural activities in summer. Considering that Venice and Toronto film festivals would be held in the future, Cannes insisted on the cinema screening mode and finally decided to stop.

Closure does not mean disappearance.

In Cannes in summer, the sea breeze, golden beaches and swaying palm leaves … Although we can’t see the competition on the red carpet this year, we can’t see how many minutes of applause lasted in the movie palace, which film was the highest and lowest score in the field, and who won the Palme d ‘Or award in the end … … However, Cannes still launched a shortlist of 56 new films.

This is an unprecedented film list.

Unlike previous years, it is no longer divided into main competition unit, non-competition screening, a kind of attention unit, midnight screening and special screening. All 56 films are put into an official unit and uniformly labeled as "Cannes Official Selection".

These selected films are divided into seven categories: loyalists, new visitors, short films, first feature films, documentaries, comedies and cartoons.

Among them, some films will be released in autumn and winter this year, and some will later go to Toronto, Locarno, San Sebastian, new york, Tokyo and other film festivals to participate in competitions or screenings.

Cannes is closed. What’s the point of this film list?

Stamping 56 new films is not only to improve the quality of these films, but also to promote their better performance in the international sales market.

"Push the film to the center of the world, and we will witness the powerful existence and amazing vitality of the film!" Fu Mao said that this is the mission of Cannes Film Festival as always.

Is the film festival "explosive" coming?

On the Cannes stage, Chinese films are still not absent.

Last year, there were equal teams, and this year, two teams were selected — — And.

"Band of Seven" is directed by Sammo Hung, Xu Anhua, Tan Jiaming, Yuan Heping, Du Qifeng, Lin Lingdong and Tsui Hark, and seven big-name directors in China Hong Kong film circle.

The film was successfully approved at the end of last year. According to the synopsis of the story, it is a collection of short films paying tribute to "film", which records stories belonging to different generations with film, similar to "assorted films" such as "I love you in Paris".

The original name of Band of Seven is Eight and a Half, which was announced as early as 2015. Eight and a Half comes from Ferini’s classic of the same name. The title refers to both the number of films directed by Ferini and the ninth film that Guido, the hero of the film, has not finished shooting.

The name "Eight and a Half" has a misty complex, and it also points to eight directors. Originally, John Woo was involved, but due to physical reasons, the film had to be renamed. In addition, Lin Lingdong, the director, died in 2018, and some of his films were finished before his death. The Band of Seven also became Lin Lingdong’s posthumous work.

There are both Hong Kong film veterans and mainland star faces in the film list. Wei Shujun, the young director’s first feature film, "Wild Horse with a mane", successfully won the official entry mark of Cannes.

This is the second time that Wei Shujun became attached to Cannes. In 2018, he won the special honor award of Cannes short film competition unit for his short film.

"Yanbian Teenager" shows the realistic creative style and concerns about the theme of teenagers’ growth. This feature film also continues to focus on the story of teenagers’ youth, starring Zhou You and Zheng Yingchen, telling the story of Akun, who is about to graduate, whose life has changed after he met his second-hand jeep.

In terms of foreign films, several popular films were selected without accident, keeping the basic disk of Cannes.

The "Loyalist" category refers to the frequent visitors who have been selected to Cannes. Wes anderson’s is the hottest, and Hollywood is full of stars. It was very likely to appear as the opening film.

According to the official introduction, this is a love letter dedicated to 20th century journalists, with three story lines. alexandre desplat praised wes anderson as the best in his career. The film is also likely to be shown at the Toronto Film Festival later.

A familiar face from Cannes and Naomi Kawase, a Japanese female directors, was selected for the "N th time". The new film "Dawn is Coming" tells the story of a couple who can’t have children adopting an early pregnant female student, and will explore the meaning of "becoming a mother" and "mother herself" from multiple perspectives.

Another "Cannes lineal", French female directors Ma? Wenn’s "Reaching the True Love" can’t be ignored. She won the jury award in Cannes for "Police Officer" and the romantic film was also shortlisted in the main competition in Cannes and won the best actress award.

Lars von Trier’s good brother, Danish director thomas vinterberg, one of the initiators of the "Dogma 95" film aesthetic movement, was selected as the "Alcohol Plan" eight years after he violated the Cannes Film Festival. The hero is still mads mikkelsen, the "uncle" in the old work, telling the story of high school teachers’ persistent drunkenness experiment and discussing the middle-aged crisis.

Ou Rong’s "Summer of’ 85" is like another film, which leads the audience back to the summer of 1985 and follows the growth time of two teenagers with retro music, cheerful dance and heat wave in the sun.

Prior to this, Ou Rong was shortlisted for the main competition unit in Cannes for three times, and all of them failed. Although I was selected this time, I regret that I can’t compete for the award.

Steve mcqueen, the British director of Twelve Years a Slave, brought two series movies, Lover’s Rock and Mangrove. These two works are from the first two episodes of the BBC series "Little Axe", which was originally planned to be six episodes and five hours long, and finally expanded into five feature films, focusing on the lives of the first generation of British West Indian immigrants.

The category of "new arrivals" refers to the works of directors who were shortlisted for Cannes for the first time. Among them, the works of British director Francis Lee have gained a lot of attention, and Kate Winslet and Saoirse Ronan performed together, and the casting configuration is very eye-catching.

In terms of feature film debut, in addition to the China film Wild Horse with a mane, the directorial debut of Viggo Mortenson, starring Aragon, is also worth mentioning. The film premiered in Sundance and received good reviews. Variety describes that mortensen’s film style is very similar to Eastwood’s later works.

If the Cannes Film Festival is not cancelled this year, we can also see the historic picture of Pixar and Ghibli, two world animation brands competing together.

Soul is the second work released by Pixar after "1/2 Magic" this year. The quality of "1/2 Magic" is not satisfactory, and more fans place their hopes on this musical animation.

Soul is created by a team, and his creative concept is similar to Inside Out+.This paper discusses the meaning of "death" and "soul".

On the other side is Miyazaki Hayao’s son Goro Miyazaki’s animated film Aya and the Witch, which was personally supervised by Miyazaki Hayao and Ghibli’s first full 3D+CG animated feature film. The original author’s children’s novel of the same name is adapted as a blueprint, telling the story of Aya, a young girl, who was adopted by a mean witch.

For a long time, Goro Miyazaki can’t escape the comparison between him and his father. In those days, his feature-length debut "The Legend of Earthsea" suffered a lot of bad reviews, which made him once devastated. Can he hold his head high and create his own light this time?

What’s the wind blowing in Cannes this year?

In the past, the number of short-listed films in the main competition unit of Cannes was about 21. Judging from these officially selected films, according to the standards of previous years, less than ten films could be selected for the main competition unit.

On the one hand, some films that can wait until next year will choose to participate in the Cannes Film Festival in 2021 and launch an impact on the awards.

Including Leo Calaque’s song and dance films with adam driver and marion cotillard, paul verhoeven’s nun film Our Lady, Bruno Dumont’s It’s Half a Sunny Morning and Serebrennikov’s Flu in Petrov.

On the other hand, some popular films have not been made or are not loyal enough. Because Cannes cooperated with Venice to skip tickets, they are likely to run out to attend the Venice Film Festival in September, the Berlin Film Festival in early 2021 or other film festivals.

For example, Memory, directed by Ildikó Enyedi, hit the rocks by Sophia Coppola, Bergman Island by Mia Hansen Love, Three Stories by nanni moretti, a frequent visitor to Cannes, and the spy’s wife by Kiyoshi Kurosawa.

Compared with the past, this is a film list that has been greatly discounted in terms of heat and topic, but it has also created many new records.

According to reports, this year, a total of 2,067 films signed up for the official unit of the Cannes Film Festival, and the number of registrations exceeded 2,000 for the first time. In 2010, the number was only 1,665.

The range of participating countries and regions is also expanding. This year, films from 147 countries and regions signed up, compared with 138 in 2019, an increase of 9.

Among 532 films directed by women, 16 films directed by women were selected, which is more than before, indicating that the quality of female directors’s works has been improved.

At the same time, Cannes also began to pay attention to comedy types, and specially recommended five French comedies in the film list. Whether this number will become more next year can be further seen.

However, the biggest feature of this film list is the support for new directors, with 15 directors’ first films accounting for 26.7% of the total, exceeding the previous data.

Whether it’s because this year’s popular films and the works of direct directors gave up their seats, Houlang people have more opportunities to enter the room and make their mark, especially during the epidemic, which is more encouraging for these newcomers.

　"We have never had so many filmmakers selected for the official unit for the first time, which proves the vitality of the film and the investment and support of the film festival for future films," Fu Mao said.

Cannes Film Festival is destined to write a short story in 2020, and the appearance of this official shortlist has brought comfort and vitality to filmmakers and fans. As Fumao said, "Le cinéma est vivant", the spirit of Cannes has not disappeared, and it still exists this year.

Waiting for May next year, the lights will go out, the curtain will open, the music will ring, the screen of the movie palace will flash, and the Cannes Film Festival will officially return!

　　"Mom, everyone in the world has it. It is said in the song that a child with a mother is like a treasure, and a child without a mother is like a grass. I am ‘ Grass ’ … …” It was Dong Dong (a pseudonym), a sixth-grade primary school student of Nanyang School in Shuyang County, Suqian City, who wrote these words.

　　China Jiangsu Network November 17 th Dongdong’s mother was a taxi driver before her death. In the early morning of a month ago, she accidentally rushed into the river while driving, and her body was salvaged a few days later. "My family has been hiding it from me, but I already know it. That’s what I heard when I was asleep." I hid everything in my heart, and in a later exam, I wrote all my thoughts and disappointments about my mother in my composition.

　　This article made the marking teacher cry and couldn’t help posting it online. Soon, the official WeChat forwarding of the traffic patrol brigade of Shuyang County Public Security Bureau touched more netizens.

　　On October 29th, in a class test, Dongdong wrote this composition named "Mom, I want to tell you".

　　In the interview, Dong Dong’s class teacher, Mr. Shen, told the reporter that the teacher who corrected the composition at that time gave her this composition for the first time. "I couldn’t stand it in the middle of it, and several of our teachers cried."

　　Teacher Shen said that the teachers were very touched after reading the article. She is also a mother herself. Although she knew what happened to Dongdong’s family for a long time, and because she was afraid that the child would find it difficult to accept it, she always cooperated with the child’s father to hide it from him. I didn’t expect Dongdong to express it through composition.

　　Mom, I want to tell you.

　　Mom, everyone in the world has it. It is said in the song that a child with a mother is like a treasure, a child without a mother is like a grass, and I am "grass".

　　I lost my mother 11 days ago. My mother, a taxi driver, had a car accident on a bridge to Juwei 11 days ago and was drowned in the water. It took four days to salvage it. At that time, my mother was already dead.

　　Mom, you don’t know that I still have a lot to say to you, but you have passed away, and I learned a lot during the five-day funeral. I also understand the lyrics: children with mothers are spoiled, while children without mothers are as tenacious as a grass.

　　I didn’t cry, because people let nature take its course in this life. Since I have arranged this road for you, I must go on, but I am still very sad that my mother has left.

　　I have a lot to say before, and my family has been keeping it from me, but I already know it, which I heard when I was asleep. Mom, I’m so sad that I hope you don’t leave. Our harmonious family of four has been strongly separated. I really hope that something will happen to you in a few hours, and then you will be rescued immediately, but it didn’t. Mom, how I wish I could give you a pension.

　　Mom, please go!

　　For Dongdong’s family, October 17th this year is undoubtedly a nightmare. As Dongdong wrote in his composition, this nightmare tore apart the original family of four.

　　Dongdong’s parents are taxi drivers, and two people work in shifts. My father, Mr. Zhou, works in the day shift, and my mother, Ms. Shen, works in the night shift. Dongdong also has a sister who is studying in college.

　　On the evening of October 16th, Mr. Zhou gave his car to his wife and went home to take care of the children. The reporter learned that in the early morning of October 17, Ms. Shen received an order in Shuyang County, and the guests were going to the local Qianji Town. On the way back, the car had an accident when it passed the south bridge of the original 205 National Road Cross Street. "The car plunged into the river." Xu Gang, a policeman of the Traffic Patrol Brigade of Shuyang County Public Security Bureau, told the reporter that it was early in the morning and there were few pedestrians on the road. Workers in a car repair shop not far from the scene of the accident called the police after hearing the noise. Although the police quickly rushed to the scene and carried out salvage, only one empty car was salvaged.

　　At 6 o’clock that morning, Mr. Zhou got up and sent Dongdong to school. "At 7 o’clock, the taxi company called to ask me if there was anything wrong, saying that my car fell into the river and there was no one on it." Mr. Zhou said, "At that time, my legs were weak, and I even preferred that she was kidnapped by the bad guys. At least, if she is kidnapped by gangsters, she still has a chance to save her. I really dare not face the fact that she is no longer there. "

　　However, the monitoring on the taxi showed that Ms. Shen was the only one in the car. Worried that Dong Dong, who is only 11 years old, can’t accept it, Mr. Zhou decided to hide from his children for the time being.

　　In the following days, Mr. Zhou and his relatives were busy salvaging his wife’s body near the scene of the accident. At 2 o’clock in the afternoon of October 21, Ms. Shen’s body was salvaged ashore in the river 3 kilometers away from the scene of the accident, and the family was extremely sad.

　　"Mom passed away."

　　"I probably guessed … …”

　　After two simple conversations, Dongdong went back to his room to do his homework. Although the bad news brought by his father made his eyes red instantly, he didn’t cry immediately. At that time, Mr. Zhou, who was in a mess in his mind, didn’t notice the difference of his son. "His grandmother told me that she heard the child crying in the house in the middle of the night and covered her head with a quilt." Mr. Zhou said that Dong Dong and his mother are usually closer, and sometimes they deliberately spoil their mother, but since his wife died, Dong Dong seems to be a different person.

　　Children who are only 11 years old, whether at home or at school, behave in a mature and steady way. "There were many relatives at home in the first few days, and I probably guessed from their expressions that something had happened at home, so I couldn’t sleep at night and just heard what the adults said … …” Afterwards, Dongdong told his father: "The whole family is already very sad. I must act mature."

　　On November 6, Mr. Zhou learned about this composition written by Dongdong from Dongdong’s class teacher, Mr. Shen. "I asked his aunt to read it to us, and the family cried bitterly." At that time, Dongdong’s father, aunt and grandparents were present, and the composition was not finished, and the whole family had already cried into tears.

　　In the interview, Dongdong’s family told the reporter that this composition is an expression of children’s emotions. After reading it, I didn’t feel too gratified by the maturity and cleverness of the children, because the price was too high. Children of this age should be spoiled and playful with their families, so the most direct feeling of family members about these changes is actually distressed.

　　"This mature and clever transformation may also be a kind of fragility." Teacher Shen, Dongdong’s class teacher, said that he has been observing Dongdong and talked to him. Although he is very mature, he is still a child. Take this test as an example. Dongdong not only expressed his thoughts about his mother in his composition, but also wrote a passage in a reading comprehension question: "I really want to pick a star for my mother to illuminate, I want to pick the sun for my mother to warm her, and I want to pick ginkgo for my mother to eat."

　　After seeing Dongdong’s composition, the marking teacher was very touched and couldn’t help posting it online, which quickly triggered frequent forwarding by netizens. The reporter learned that on November 11, the official WeChat of the Traffic Patrol Brigade of Shuyang County Public Security Bureau also forwarded this article.

　　"For many car owners, when things don’t happen to them ‘ Traffic safety ’ It is a slogan, but when it really happens, it is bad news for any family. " The police of Shuyang Traffic Patrol Brigade said that the purpose of forwarding this article is to hope that everyone should also think about the importance of traffic safety while being moved.

　　The reporter learned from the Xiangyang Traffic Patrol Brigade that traffic safety has always been the focus of the traffic police department’s propaganda, but for many car owners, the traffic police department found the same problem: novice drivers are naturally very careful when they first get on the road, but once they think they are "old drivers", they have a lot less scruples when driving, and bad driving habits such as smoking, talking on the phone and even fatigue driving come out, and once an accident occurs, the price will be high.

　　The writer of this article is @ A Dai of Xiaowan family.

　　The ugly idolize dog is here.

　　Remember the "Do Min Joon" from the stars seven years ago?

　　He’s back with his ABS!

　　Therefore, the new drama was reported as "too large", Xiaowan:? ? ?

　　Speaking of it, as a rare "three-good student" with good acting skills and high popularity, the degree to which Kim Soo Hyun cherishes feathers is staggering.

　　After "You from the Stars" spread all over Asia, the only works he starred in in six years wereA play "The Producer"andA movie "Real".

　　After retiring from the army in July 2019, he was also cautious in the choice of comeback works, and finally took over this "Although it is mental illness, it doesn’t matter" from the beginning of the title of the play.

　　The new drama started on June 20th. After finishing six episodes, Xiaowan couldn’t help but sigh: This brother is so good at choosing scripts!

　　It doesn’t matter though it’s mental illness.

　　The play is produced by Netflix and TvN, and directed by Shin-woo Park who has worked with Cho Jung Seok (Jealousy Avatar) and Park Bo Gum (Boyfriend).

　　But unlike such sweet romantic dramas as Jealousy Avatar and Boyfriend, It doesn’t matter though it’s mental illness.Dark fairy tale love drama.

　　The leading actor, Wen Gangtai (Kim Soo Hyun), is a psychiatric nurse practitioner who has been dealing with various mental patients for ten years.

　　And this is not his biggest burden: Wen Gang’s parents died when he was too young, and he lived alone with his autistic brother.Taking care of his brother is his "reason to live".

　　Gentle and restrained, coupled with rough life experience, the "angel-like" Wengangtai always gains the pity and care of the people around him, and his life can be regarded as bitter but warm.

　　The heroine, Gao Wenying (Seo Yea Ji), is completely the opposite of Mrs. Wen Gang: she is a popular fairy tale writer, rich and popular, and everywhere she goes, she is full of stars.

　　But because of suffering fromAntisocial personality disorderCoupled with the shadow left by his father’s violence and his mother’s suicide when he was a child, Gao Wenying developed a defiant, arrogant and reckless style.A "witch" who pursues extreme egoism to the end.

　　Angels and witches meet unexpectedly, so it’s meant to be, right?

　　No, it doesn’t matter if it’s mental illness.Two disabled people heal each other.The story.

　　Pay attention to personality defect groupsThe setting of+the highly anticipated Cass, this drama was not unexpectedly one of the ratings in the same period on the opening day.

　　On the day of the premiere, the female host’s exquisite makeup and high-cold gas field were eye-catching, and the male host also brushed a wave of heat through the abdominal muscles.

　　However, with the deepening of the plot, the characters of Wen Gang Tai and Gao Wenying and the long story formed by this character have become a greater motivation for the audience to follow the drama.

　　Gao Wenying’s "abnormality" can be seen at a glance.Anti-social personality disorder makes her unable to communicate with people normally, arrogant and rude, and her language is vulgar.

　　At the beginning of the series, she directly explained her experience with a Gothic animation: she was imprisoned as a monster since she was a child, with no friends and no freedom.

　　And her fairy tales are alsoDark fairy tale style with cruel words and bloody illustrationsAlthough it is very popular, it is often on the verge of "no sale".

　　After getting to know Mrs. Wen Gang, a nurse, Mrs. Wen Gang will often comfort her emotions and help her calm down in a professional way when she is rude and violent.

　　Because of the relationship between the patient and nurse practitioner, the audience will initially think that the "mental illness" in the title refers to the heroine Gao Wenying.

　　But as a "patient", Gao Wenying has her own way of relieving:Every work of hers tells her own story.

　　Speaking of the dark past and accepting it, Gao Wenying has taken the first step of "healing".

　　In addition to the autistic brother who is receiving treatment and the anti-social personality woman who is self-resolving, Kim Soo Hyun playsWengangtai is the "patient" who hides the deepest.

　　Because my brother is autistic, Mrs. Wen Gang was asked to take care of and protect her brother from an early age.

　　Mother will even look Wen Gangtai directly in the eyes and tell him:I wanted someone to take care of my brother, so I gave birth to you.

　　Wen Gang, who was born because he was useful, was taught to live for his brother since he was a child, and only his brother’s mother let him.Accustomed to suppressing one’s emotions and desires..

　　For more than ten years, I have been circling around my brother, which has made him a typical paying and even flattering personality.

　　After his mother died unexpectedly, Mrs. Wen Gangtai was left with her brother, who could not perceive emotions. He tried to teach him to judge others’ emotions through expressions: what is happiness, what is anger, what is disappointment …

　　Because my brother learned to read and read, over time, Mrs. Wengang would habitually smile as long as she faced her brother. He said, "It’s not hard to smile at people anyway.”。

　　Having lived with my brother for a long time, and having a professional nurse practitioner qualification certificate, such Wen Gang seems to be very good at dealing with people with mental/mental state deficiency.

　　But in fact, from childhood, he failed to learn to talk to himself and how to express himself correctly.

　　Wen Gangtai is also a "patient". He doesn’t know how to love himself.

　　As his friend Jae-soo said: You laugh like a clown.

　　One sentence tells the real life and psychological state of Wengang.

　　On the surface, one of them is an angel and the other is a witch.

　　In the previous episodes, the painting styles of Wen Gang Tai and Gao Wenying in the play are also two extremes:

　　The man lives in poverty and his brother is ill, but the company of his brother and friends fills his side with a dull and warm atmosphere;

　　The scene in which the heroine appeared alone turned into a horror suspense film in seconds, with arrogance during the day and nightmares at night, which was completely miserable.

　　But just like BGM’s lyrics, "You breathe in my body and pour out your thoughts; I lost everything and breathed in your shadow. "

　　The spiritual world of Wen Gang Tai and Gao Wenying is actually two sides of the same coin set in "Although it is mental illness, it doesn’t matter".

　　They represent the two extremes of human inner feelings, and they are all eager for the other side of themselves, so they will attract each other and get closer and closer.

　　So this drama is actually aboutAngels and witches attract each other, heal each other, and finally become human beings.The process.

　　This process is actually quite cruel.It is extremely difficult to admit that you are missing and need to be cured.That’s why society is afraid to avoid "mental hospitals" and "mental patients".

　　Therefore, the whole drama "It doesn’t matter although it’s mental illness" is trying toCreate a "divorced from reality" atmosphere.

　　The world in the eyes of autistic brothers is a world that will interact with themselves like cartoons.The model in the window will wave, the clouds on the mural will glow, and everything in the world will change rapidly with his mood;

　　The lights in the mental hospital are always flickering, and the patients’ various auditory hallucinations are shaped into a horror film atmosphere;

　　Gao Wenying’s castle is like a fairy tale with dark style. The witch and princess live in the world at the end of the forest …

　　This aspect is presenting what we often say.Psychopaths’ own world",give the audience a direct impact.

　　On the other hand, these seemingly incompatible environments are actually revealing the final direction of the play:

　　All this is true. There are always people who live like this.

　　As for how to peel off the layers of fog and disguise to see the truth, "Although it’s mental illness, it doesn’t matter" also gives the answer:

　　There are a lot of close-ups of faces and even partial close-ups of eyes in this play.

　　Do you still remember Mrs. Wen Gangtai’s training for autistic brothers? Expression can judge people’s mood.

　　Even if the expression can be disguised, the true inner emotions will be revealed through the eyes.

On the morning of February 3rd, under the guidance of Sichuan Provincial Department of Commerce and sponsored by Meishan Municipal Bureau of Commerce and Dongpo District Government of Meishan City, "Weimei Sichuan Xiangpiao Dongpo" 2023 Meishan Food Activity and Meizhou Famous Chef Award Ceremony were held in Impression Water Street of Dongpo, Meishan, which also marked the official launch of 2023 Meishan Food Activity.

The event lasted from February 3rd to February 5th (Lantern Festival on the 15th day of the first month). During the event, hundreds of food merchants were attracted to participate. The products included Tianfu famous dishes, Dongpo famous dishes, non-legacy foods, special snacks, innovative products, rich American foods and high quality and low price.

In the past, the hebang cuisine in Sichuan cuisine refers to the food taste along the Minjiang River. How to connect the cities along the Minjiang River into a modern food corridor? On the same day, the food industry associations in Chengdu, Meishan, Deyang, Ziyang and Leshan signed a strategic cooperation agreement to jointly build a "Minjiang Food Corridor in Metropolitan Area", which will rely on the opportunity of the urbanization development of Chengde Meizi to strengthen cooperation and exchange and innovative research and development of dishes, jointly inherit Sichuan cuisine culture and develop Tianfu cuisine. The event also publicized the local standards of Dongpo cuisine in Sichuan Province (Meishan City).

In recent years, Meishan City has adhered to the "Meishan Excellent Talents Project" as the overall plan, gradually implemented the Meizhou local talents cultivation plan, carried out the cultivation and selection of Meizhou famous craftsmen and Meizhou famous chefs, and awarded the second batch of Meizhou famous chefs. (Bai Yang reporter Zhang Meng)

After a lapse of one year, on May 15th, the US government once again used state power to block Huawei. Compared with the impact of last year’s "516 entity list", this attack is more accurate and thorough.

To put it simply, if any semiconductor company in the world wants to produce chips for Huawei, it needs to obtain permission from the United States first.

Why can the US government be so lenient? Because every semiconductor company in the world is using the software and technology of American companies more or less. This is the so-called "long arm jurisdiction".

Are semiconductor enterprises in China bound by this? Theoretically, this is the case, because some underlying technologies in China’s semiconductor industry chain can only adopt American technologies.

The United States’ comprehensive restriction and upgrading of Huawei’s chip industry covers the upstream software of chip design, the upstream equipment of chip manufacturing and the 7nm chip manufacturing mainly produced by TSMC. The US Department of Commerce has carried out a fixed-point precision strike on all links of Huawei’s chip industry chain.

The first thing is the upstream EDA software of chip design. Although Huawei can design chips, the high-end software EDA tools for IC design are still basically monopolized by three American companies: Cadence, Synopsys and Mentor. In the China market, these three EDA software companies occupy 95% market share.

As far as Huawei is concerned, since May 16 last year, the cooperation between the three major EDA manufacturers in the United States and Huawei has been terminated. This means that Huawei has not obtained new tools and new upgrade services since then, but it can continue to use EDA tools that Huawei has purchased and authorized. In other words, at present, Huawei Hisilicon can also use the old version of EDA for IC design.

However, in the long run, the localization of EDA software is imperative. Some analysts believe that the technical restrictions in the United States are bringing opportunities to the development of domestic EDA software in China.

Having said that, we must also be soberly aware of the technical gap between China and the United States in EDA software and the difficulty of domestic substitution. But at the same time, we should give up the illusion of "compromise and surrender" and seek the possibility of technological breakthrough.

Why is EDA software important?

If chip manufacturing is compared to building a building, IC design is the design drawing of the building, and EDA software is the design tool of this drawing, but the complexity of EDA software is n orders of magnitude higher than that of architectural design software.

EDA, the abbreviation of Electronics Design Automation, is a computer-aided design software system developed on the basis of electronic CAD technology, which integrates the latest achievements of applied electronic technology, computer technology, information processing and intelligent technology to automatically design electronic products.

Using EDA tools, electronic designers can design electronic systems from concepts, algorithms, protocols, etc., and can automatically process the whole process of electronic products from circuit design, performance analysis to designing IC layout or PCB layout on the computer. EDA technology can be widely used in many fields such as electronics, communication, aerospace, machinery and so on.

With the development of integrated circuit technology, EDA software is more and more synonymous with "chip design software tools" by the industry.

That is to say, EDA software is an important tool for chip design. However, due to the complex technology, fine division of labor and multi-technology synthesis of chip design, EDA software does not refer to only one or several softwares, but involves nearly a hundred different technologies and covers a variety of "point tools" software tool clusters.

EDA software can greatly improve the efficiency of chip design, and also has applications in chip manufacturing, packaging and testing. EDA, semiconductor materials and equipment together constitute the three foundations of integrated circuits.

Today, there are at least hundreds of millions to billions of transistors on a chip, and continuous simulation and verification are needed in the design process, which are inseparable from EDA software. Without EDA tools, no matter how high the level of chip designers is, there is no place for them.

From the basic role of EDA in chip design and manufacturing, its importance is self-evident; From the complexity of EDA software, its technical realization is very difficult.

Specifically, the front-end design of the chip includes chip specification formulation and detailed design, HDL coding, simulation verification, logic synthesis, static timing analysis (SAT) and formal verification. The back-end design includes DFT, FloorPlan, clock tree synthesis (CTS), Place & Route, parasitic parameter extraction, physical verification of layout and so on … …

Judging from the tools used in these design processes, it is almost monopolized by three American companies, Cadence, Synopsys and Mentor, which may disappoint many people who call for the localization of EDA software as soon as possible.

So, what challenges does the domestic substitution of EDA in China face?

What are the difficulties faced by EDA localization substitution?

We must first understand the characteristics of EDA industry. EDA is an extremely important key link in the integrated circuit industry chain, but it is also a highly centralized industrial link with relatively small output value.

In 2018, compared with the chip industry of nearly 500 billion US dollars, the market size of the whole EDA is only 9.715 billion US dollars. Among them, 70% of the market share is occupied by EDA giants Synopsys, Cadence and Mentor Graphics under Siemens. The global EDA industry has formed an oligopoly pattern of the three giants. In the China market, the three giants account for more than 95% of the EDA market share, with a higher concentration.

This has not only greatly squeezed the development space of China’s EDA industry, but also seriously affected the pace of domestic research and development of EDA software in China. In the 1990s, when the United States lifted the ban on EDA in China, the advanced EDA software from the United States quickly came to China, attacking the city all the way, which disrupted the pace of independent research and development of EDA in China, and "market for technology" became the path dependence for the next decade.

Compared with American high-end and mature EDA industrial chain, what are the difficulties in the development of EDA industry in China?

The first is the technical threshold. EDA tool is a "multi-tool" software cluster. At present, Chinese enterprises have achieved breakthroughs in some tools, but at present, more technology needs to be accumulated in the complete and available full-process tool chain, which cannot be completed in a short time.

Secondly, the technology integration is high. EDA is the result of long-term cooperation among chip design companies, fabs and EDA software vendors, which requires a lot of talent investment, mathematical optimization and experience accumulation, and cannot be achieved overnight. At present, many EDA enterprises not only provide EDA software, but also provide IP design, which can not only reduce costs, but also improve IP quality by developing some customized EDA functions, and become the main popular mode at present. Our country’s integrated design ability in advanced process is obviously behind the foreign 2-3 generations.

Once again, it is the talent threshold. In terms of EDA software R&D talents, there are not many universities in China that set up EDA majors, and the Internet and financial industries attract a large number of software development talents, which leads to a serious shortage of EDA software R&D talents.

Finally, China also needs to strengthen the intellectual property protection of EDA technology.

At present, EDA has become the key bottleneck for China’s semiconductor industry to achieve autonomous control. In the field of EDA software, China has owned enterprises such as Huada Jiutian, Guangliwei, Xinhe Technology, Lanhaiwei, Jiutongwei, Bodawei, Jilun Electronics, Kejingda, Chuanglian Zhiruan, etc. It is necessary to achieve a comprehensive breakthrough from "point" to "surface" in overcoming the above problems.

How to break the situation of EDA software localization replacement?

Let’s look at the current situation first. Before the 516 entity list incident last year, Huawei obtained the permanent authorization of EDA tools at that time. Because these EDA software can lead the actual chip manufacturing process for two or three years, the EDA ban will not have much impact on Huawei’s chip design in the short term.

However, if Huawei can’t get the updated and upgraded EDA tools because of the continuous technology export ban, it will greatly restrict Huawei’s iterative development in higher-end chip technology.

Not long ago, Huawei tried to design chips jointly with stmicroelectronics (STM.N). One of its purposes was to obtain EDA design technology to find technology records beyond the US technology ban. However, with the intensification of this round of sanctions, this cooperation may also be terminated.

At present, Huawei can only transfer 14nm chip manufacturing orders to domestic SMIC. In the manufacturing of 5nm and 7nm chips, SMIC still lags behind TSMC’s technology and process. One of the big reasons is that domestic manufacturers who provide chip design software for SMIC cannot achieve a breakthrough in the design of high-end chips.

In the long run, it is imperative to replace EDA software in China. The new round of technical restrictions in the United States has strengthened the determination and speed of China’s semiconductor industry’s autonomy. And a series of factors are also quietly promoting the development and break of EDA software industry in China.

First of all, the leading EDA enterprises in China are receiving a number of grants and strategic investments from the state and investment institutions.

On the evening of May 15th, SMIC announced that the second phase of the State Integrated Circuit Fund and the second phase of the Shanghai Integrated Circuit Fund had injected US$ 1.5 billion and US$ 750 million into SMIC South respectively. This will greatly expand the production capacity of 14 nm wafers.

Similarly, the country is also increasing the resource inclination of EDA industry and promoting the independent development of EDA software. Among them, Guowei Shenzhen’s special sub-project "Development and Application of EDA System in Chip Design Whole Process" ("the project") has been approved by the national major science and technology special project, and will receive a total of about 400 million yuan from the project. As the largest EDA company in China, Huada Jiutian has also received several rounds of investment of several hundred million yuan from various investment institutions in China in recent years.

In terms of policy support, in the face of the situation that domestic EDA software is not used, domestic EDA software is given a certain purchasing inclination. For example, the "Several Measures on Accelerating the Development of Integrated Circuit Industry" issued by Shenzhen recently introduced the first domestic policy to explicitly support EDA R&D, including funding incentives for EDA R&D and subsidies for purchasing domestic EDA software.

Secondly, at the market level, the new development of domestic IC industry also brings some opportunities for the development of domestic EDA software.

At present, new technologies such as 12nm and 7nm are widely used in domestic chips, which urgently requires domestic EDA software to develop products comparable to international manufacturers. Only in the design based on the most advanced technology, it is possible to find the defects of the process and potential product opportunities. Of course, this poses a certain challenge to domestic IC design enterprises, but in the case that the United States can "get stuck" at any time, we must pay some trial and error costs to promote the progress of domestic EDA software.

The rise of new applications such as AI chips and IoT chips has brought new challenges to the existing EDA industry and chip design process, and also brought many new technical research directions to small and medium-sized EDA companies, which has become a new opportunity for them to break through the barriers of EDA giants.

Thirdly, AI technology, as a new variable, is bringing a breakthrough to domestic IC design.

Recently, Google is using AI algorithm to learn the layout of chips, so that products beyond manual design can be designed in a shorter time. Similarly, AI technology is being widely used in EDA companies. For example, Empyrean Mcfly, which was launched by Huada Nine Days ago, uses AI algorithm to accelerate IP verification, and uses AI to learn previous IP cases to verify the new IP, and the verification accuracy reaches about 99%.

In addition, if we want to look at the "broken core" incident in the United States from a longer-term perspective, we must realize that perfect property rights protection of technological innovation and mature talent training mechanism are the fundamental ways for China to achieve core technology in its own hands.

Finally, we should realize calmly that the domestic substitution of EDA software and other related core technologies in chip manufacturing is definitely not a natural thing. Think about the prosperity and decline of Japanese semiconductors, which is our lesson.

In the short term, the prohibition of existing foreign EDA software will not have a fatal impact on Huawei, but Huawei is facing a more dangerous situation because of the upgrade of the entire semiconductor technology in the United States. Actively playing games and seeking "spare tires" have become two preparations to be carried out at the same time.

In the long run, the country and the industry can no longer have the illusion of "compromise" and "seeking to let go" of the United States. All sectors of the industry must show patience and determination to invest in the development and research of basic science and core technologies.

On this more difficult road, China’s chip industry and related science and technology industries should be prepared for long-term suffering. This is especially true for EDA software industry.

　　On September 29th, the Civil Aviation Administration of China awarded the C919 type certificate to Commercial Aircraft Corporation of China (hereinafter referred to as "Comac China"). From the establishment of the project in 2007 to the first flight in 2017, and then to the completion of evidence collection, it took 15 years, and the domestic large aircraft was finally allowed to engage in commercial operations and was about to soar above the blue sky.

　　What are the advantages of domestic large aircraft? Why build your own large civil aircraft? Our reporter interviewed Comac China and relevant experts in civil aviation.

　　Have a competitive advantage in many aspects

　　— — It is not only equipped with advanced systems and materials, but also provides passengers with a more comfortable ride environment.

　　On September 29th, the type certificate certification ceremony of C919 aircraft was held in Beijing Capital International Airport, which was an important milestone in the cause of China’s large aircraft, and marked that the large passenger aircraft with independent intellectual property rights developed by China in accordance with internationally accepted airworthiness standards passed the airworthiness certification. Since then, China has a single-aisle trunk airliner that can be put into operation.

　　"C919 completed the evidence collection, indicating that its safety and reliability meet the requirements of airworthiness regulations." Li Xiaojin, director of civil aviation university of china Institute of Aviation Economics, told this reporter that the C919 successfully made its first flight in May 2017. During the flight test period of more than five years, six trial aircraft have completed a series of flight test missions in Yanliang, Shaanxi, Nanchang, Shandong, Pudong, and Dunhuang, Gansu, and comprehensively verified the power and electrical systems, verifying the safety and reliability of the aircraft in various extreme situations such as stall, natural icing, high temperature and extreme cold. At 6: 52 on May 14th this year, the seventh aircraft of C919 jumbo took off from Shanghai Pudong Airport and landed safely at 9: 54, marking the successful completion of the first flight test of the first C919 jumbo aircraft that China Commercial Aircraft Corporation is about to deliver to its first customer.

　　Whether a civil airliner can be put into commercial operation is not decided by the manufacturer, nor by the operator, that is, the airline, but by airworthiness certification. The type certificate won this time is the ticket for large aircraft to enter the aviation market.

　　After getting the admission ticket, it depends on the advantages of domestic large aircraft if they want to gain a foothold in the aviation market.

　　C919 is equipped with advanced systems and advanced materials. According to Comac of China, the C919 wing design adopts supercritical airfoil design independently developed, which can reduce drag by 5%. The use of advanced materials such as Al-Li alloy and composite materials makes the structure lighter, which greatly improves the safety, economy and environmental protection of the aircraft. At the same time, it is equipped with advanced airborne systems and engines with superior performance.

　　For passengers, the wide fuselage of the C919 will provide more seating space. At the same time, it adopts high-efficiency air filtration system to provide passengers with high-quality fresh air, and the cabin lighting adopts humanized scene lighting design to create a warm and considerate comfortable environment.

　　The C919 is aimed at Airbus A320 and Boeing 737 series models, and adopts single-channel narrow-body layout, with 158 to 192 seats and a range of 4,075 to 5,555 kilometers. At the same time, the C919 is safe and reliable, backed by the vast China market, and has unlimited potential.

　　At present, C919 has accumulated more than 800 orders from 28 customers. "Before type certificate was acquired, there were more than 800 orders, which was quite impressive. The safety, economy, comfort and other aspects of the C919 are relatively suitable for market demand, and are suitable for domestic long-distance routes and neighboring Southeast Asian international routes. " Li Xiaojin commented like this.

　　An important milestone in China’s commercial aircraft manufacturing industry

　　— — It is a large jet civil aircraft developed by China and with independent intellectual property rights.

　　Why build a large domestic civil aircraft? Aviation manufacturing industry is known as the "flower of industry", with long industrial chain and high added value, involving hundreds of professional categories, which has high requirements for industrial capacity. Among them, the R&D and manufacturing capacity of large passenger aircraft is an important symbol of a country’s aviation manufacturing level and is also regarded as the embodiment of a country’s overall strength.

　　In the past ten years, the C919 research team insisted on independent innovation and open cooperation, successively conquered a number of key technologies, formed a number of core capabilities, tempered a number of talent teams, promoted a number of industrial development, and formed a capability platform to support the independent development of China large aircraft.

　　The person in charge of Comac China said that through the development of C919 large passenger aircraft, China has completed the whole process of design, manufacture, test, flight test and airworthiness certification for the first time, and has the ability to develop large passenger aircraft according to internationally accepted airworthiness standards.

　　C919 adopts the mode of "main manufacturer+supplier". As the main manufacturer of domestic large aircraft, Comac China is responsible for the design and development, system integration, final assembly, airworthiness certification, customer service and marketing of C919. Comac China conducts supplier selection and management for airframe structure and airborne system equipment nationwide. The structure of C919 is designed by Comac of China, and manufactured by many domestic enterprises, with completely independent intellectual property rights. The engine is provided by CFM, a US-France joint venture company, and the avionics system is provided by Angji Avionics, a Sino-US joint venture company.

　　The development of domestic large aircraft is also an important aspect to meet the dual needs of the national economy and development strategy. Li Xiaojin said: "The civil aviation industry is a national basic and strategic industry. Buying a large number of foreign aircraft makes our air transportation industry subject to people. At the same time, the price of Airbus A320 and Boeing 737 series aircraft is about $110 million to $120 million. If you buy hundreds of aircraft every year, it will cost tens of billions of dollars, which is relatively high. With the commercial operation of C919, it will accelerate the integration of upstream and downstream industries, amplify the industrial correlation effect of civil aviation and aviation manufacturing, and further improve the overall economic development quality. "

　　The aviation market in China is large.

　　— — In the next 20 years, China’s demand for passenger airliners is estimated to be 9,084, worth about 1.39 trillion US dollars.

　　At present, Airbus and Boeing account for the bulk of the global civil aviation aircraft market with more than 100 passengers. After C919 is put into commercial operation, what impact will China large aircraft bring to civil aviation?

　　— — Create new economic growth points.

　　China’s civil aviation transportation industry is in a period of rapid growth, and the domestic market demand is great. The development of domestic large aircraft will better meet the needs of China’s economic development and people’s travel, and create new economic growth points.

　　China Commercial Aircraft Corporation Market Forecast Annual Report (2021— 2040) predicts that in the next 20 years, more than 41,429 new aircraft will be delivered worldwide, with a value of about 6.1 trillion US dollars (based on the 2020 catalogue price). China aviation market will receive 9,084 new aircraft, with a value of about 1.39 trillion US dollars (based on the catalogue price in 2020). Among the newly accepted aircraft in China aviation market, the number of narrow-body passenger aircraft will reach 6,295. As the mainstream aircraft in the civil aviation transportation market, narrow-body passenger aircraft account for about 80% of China’s civil aviation fleet and 70% of the global fleet.

　　— — Promote the upgrading and development of the industrial chain.

　　C919 is the take-off work of China’s large civil aircraft industry, and the aviation manufacturing industry chain driven by C919 has great potential. It is expected that it will drive group breakthroughs in new materials, modern manufacturing, advanced power, electronic information, automatic control, computers and other fields, and will also enable aviation high-end raw materials, subsystems and parts manufacturers to achieve performance growth. At present, more than 20 provinces, more than 1,000 enterprises and institutions and nearly 300,000 people have participated in the research and development.

　　Taking materials as an example, the application of new materials is an important aspect of the development and progress of aviation technology. The manufacturing of large civil aircraft involves composite materials, titanium alloys, high-strength steel, etc. The development of C919, and a variety of new materials are applied to civil aircraft on a large scale for the first time, which not only leads to a breakthrough in material technology, but also brings great demand to the material industry.

　　The successful development of C919 will provide more choices for airlines and customers, more opportunities for suppliers and partners, and further stimulate the healthy competition and innovation vitality of the global commercial aircraft industry.

　　The airworthiness certification is only the first step for C919 to be put into operation, and the subsequent industrialization will take a long time. Li Xiaojin said: "According to public data, there are about 50,000 transport aircraft in operation around the world, of which Boeing and Airbus each account for about 45%. In the future, C919 should also strive for the european aviation safety agency airworthiness certificate and the US Federal Aviation Administration airworthiness certificate in order to put it into commercial operation in more countries. " He said that there is still a gap between China and the world-class level in aero-engine manufacturing and avionics system design. Compared with automobile and other industries, the aviation manufacturing industry has the characteristics of high technology added value and low labor intensity, and there are certain technical barriers. The technology in many sub-sectors of the industrial chain still needs to achieve a breakthrough from 0 to 1.

　　Slow and steady, with unlimited potential, China Big Aircraft will write more wonderful stories.
