Black Technology Refresher Manual

Sheng Mingan saw Chen Jingqiu wearing the watch he gave him the next day, and Ma Guangda saw it with sharp eyes and said casually, "mechanical watch?"cool!Where did you buy it? ', I got Chen Jingqiu's answer 'Cool?I don't know where to buy it either'.

Ma Guangda understood: "A gift from a friend?"

Chen Jingqiu nodded: "Birthday gift. He specially made it."

Ma Guangda was so envious, he looked around at Chen Jingqiu's watch, and almost moved out of the microscope to observe it, and sighed from time to time: "The light material is black gold, which is more expensive than gold. It's such a big piece, it's so good." Tens of thousands. I don’t know what movement is used, but the custom-made model must use an expensive and less expensive movement, which must be old craftsmanship, otherwise who would dare to start with this large piece of black gold?”

He finally came to a conclusion: "There should be a hundred thousand mechanical watches!"

Chen Jingqiu: "Is it so expensive?"

One hundred thousand for just one watch?

Ma Guangda nodded heavily: "Absolutely! Brother Chen, your friend is really rich!"

Chen Jingqiu rubbed the edge of the watch, feeling cold to the touch, glanced at Sheng Mingan who was playing with a pen at the desk in front of him, and echoed with a smile: "It's very rich. He treats me well."

"I also want to have such a good friend." Ma Guangda drooled with envy, and looked back at Cui Chuanhe and Sha Lang: "Brothers, younger brother, I put my hope on the two of you."

Sha Lang didn't raise his head to beat the monster: "When brother catches the rich woman, half of the country will be shared with you."

Ma Guangda was moved: "There is no need to be rigid about gender."

The two looked at each other and smiled.

Cui Chuanhe's hands trembled, and he jumped up angrily: "Fuck - you two bastards! Look at your father, if I don't pour socialist red ideas into you today, I will have no face to live in this dormitory!"

Sha Lang and Ma Guangda laughed meanly, turned their heads to Cui Chuanhe: "Where is the irrigation?"

Cui Chuanhe: "..."

Cui Chuanhe: "Ah, ah, bitch!"

The three of them went crazy again.

Chen Jingqiu dragged the chair and moved to Sheng Mingan's side, behind him were three people who were huddling together, the noise couldn't break the silence of this corner.

Sheng Mingan glanced at him, took off one earphone and gave it to him: "Just get used to it."

Chen Jingqiu was speechless for a while. He thought that Sheng Mingan was only interested in studying because he was silent and not being disturbed all the time. He didn't expect that he was listening to music with earphones on.

The song is a piece of pure music, calming and peaceful, cleansing the soul, like a clear stream flowing over pebbles, soaking green water plants, making people unable to help but think of summer in the forest.

Chen Jingqiu leaned on the table and looked up at Sheng Mingan, and asked softly, "Is this watch expensive?"

Sheng Ming'an: "It's not as exaggerated as a hundred thousand."

That's tens of thousands.Chen Jingqiu didn't continue to ask, he guessed and remembered it in his heart, and was secretly delighted by Sheng Mingan's heart.

Sheng Mingan glanced at Chen Jingqiu from the corner of his eye, wondering why he keeps smiling?What is there to be happy about?

However, the way he smiled was as the system said, quite gentle.

***

During the three-day holiday on New Year's Day, Sheng Ming'an and Chen Jingqiu returned to Tianjin City. Grandpa Sheng prepared a big meal at home early and waited for them.

Chen Jingqiu first went to Sheng Ming'an's house to meet Grandpa Sheng, and was left behind after eating a big meal made by Grandpa Sheng himself. After returning to her own home, after putting down her luggage, she went to the hospital to visit Aunt Yao that night.

In the inpatient department of the city's top three hospitals, a single ward.

When Chen Jingqiu arrived, Aunt Yao was talking to someone, he knocked on the door, both people in the ward turned their heads, and the other person was Li Jiao.

Seeing Chen Jingqiu, Aunt Yao couldn't help showing surprise: "Jingqiu, why are you here?"

Chen Jingqiu went in, put a pillow behind her and said, "School is on holiday, I'll come back to see you."

Aunt Yao babbled a lot after hearing the words, telling him to take care of himself, not to send money back all the time, study is more important, not to relax during holidays, etc.

Chen Jingqiu stood beside her quietly listening to her, and after about ten minutes, interrupted Aunt Yao: "Drink some water."

Aunt Yao was distracted, and Li Jiao, who had been silent since Chen Jingqiu came in, said, "Chen Jingqiu, long time no see."

Chen Jingqiu glanced at him and responded with an indifferent expression.

Li Jiao didn't feel embarrassed, and said to himself: "I was participating in the talent show when you were admitted to HKUST, and I didn't have time to congratulate you. This time I heard that you solved a big problem in the physics world and published a paper in a top journal. Haha, I just met you last year, and I saw that you are very powerful, and you will definitely achieve extraordinary things in the future, you just missed a chance—”

"The first paper was written by Sheng Ming'an, and he also solved the problem." Chen Jingqiu interrupted him in a low voice.

Li Jiao said with a smile: "I read the interview on People's Day, and the newspaper reported that the two of you worked together. Without your help, my cousin would not be able to complete such a complicated and difficult research. If you didn't contribute, how could the paper be signed? Your name? Did my cousin take the initiative to give you half of the credit?"

He puts a lot of emphasis on 'you'.

But I heard Chen Jingqiu say: "It is true that Sheng Ming'an took the initiative to give up half of the credit to me. He signed my name in the position of the first part of the thesis because he was willing to share it with me, but even if he monopolizes the results, no one will say anything, because it is true. It is the result of his own scientific research."

Li Jiao laughed dryly: "You don't have to be modest..."

"I know how much water I have." Chen Jingqiu poured a glass of water and handed it to Aunt Yao, then turned to look at Li Jiao: "Sheng Ming'an doesn't care about fame and fortune, he regards me as a friend, so he is willing to do anything good Give me half."

Li Jiao put away his smile: "...Really?"

Chen Jingqiu responded, picked up an apple next to it and began to peel it.

Aunt Yao looked at the two of them, and in order to ease the atmosphere, she dragged Li Jiao to continue talking, but Chen Jingqiu didn't participate very much, and in the end, Li Jiao felt embarrassed and stood up to say goodbye.

As soon as Li Jiao left, Aunt Yao asked Chen Jingqiu: "Jingqiu, did you and Xiao Li fall apart?"

Chen Jingqiu was taken aback for a moment, then said, "No."

Aunt Yao: "Aren't you friends?"

Chen Jingqiu denied it.

Aunt Yao stared at Chen Jingqiu for a long time, and she held the child in front of her hand. She thought that no one knew Chen Jingqiu better than her, but sometimes she still felt that Chen Jingqiu was too deep in her thoughts.

But it is the living environment that shaped him, and he cannot be blamed for not being pure and kind enough.

Last year, Li Jiao helped her pay for her medical expenses and stood beside Chen Jingqiu with a bright smile, which was in stark contrast to the gloomy Chen Jingqiu. It was also the first time she saw Chen Jingqiu around her peers.

"I thought you two would become friends." Aunt Yao said.

Chen Jingqiu lowered her eyes, shook her head and said to Aunt Yao: "He is not, and it is impossible."

There is no second Sheng Ming'an in the world, and he only needs one trusted and beloved friend and family member.

Sheng Ming'an has already occupied the only position, and no one else can ever replace him.

Although Aunt Yao loves her children more, she still takes Chen Jingqiu's side when it comes to closeness.

Because she owes nothing to Li Jiao, but Chen Jingqiu.

She had been ill for many years, and only Chen Jingqiu worked desperately to earn money to pay for her medical expenses. For this reason, she dropped out of school, was belittled by others, and was often beaten and bruised.

Chen Jingqiu: "Li Jiao comes here often?"

Aunt Yao shook her head: "Just this time."

Apart from the first meeting in the hospital, today was the second time, and it happened that Chen Jingqiu came back, which was the reason why she did not hesitate to stand with Chen Jingqiu.

Chen Jingqiu said he knew.

Aunt Yao asked about Sheng Ming'an, and when Chen Jingqiu talked about Sheng Ming'an, he talked endlessly, until Aunt Yao became drowsy and couldn't hold it anymore, he suddenly realized that he was talking too much and shut up, helping Aunt Yao to lie down to sleep, before leaving the hospital.

Before leaving, Aunt Yao said that she was very happy to see Chen Jingqiu having a good time, and that she would like to meet Sheng Mingan if she had the chance, because Chen Jingqiu always smiled when she mentioned Sheng Mingan.

It's like a person who doesn't know it, but writes it on the corner of the eye and brow, and there is no place from the inside to the outside that no longer tells others.

When the words came to her lips, Aunt Yao hesitated, facing Chen Jingqiu's probing eyes, she chose to swallow them back.

Chen Jingqiu didn't take it seriously, closed the door and left.

Outside the hospital square is the main road. There is a lot of traffic, the street lights are bright, there are many tall buildings, and the tram roars past. When Chen Jingqiu walks to the intersection, the green light turns on. He crosses the road with the crowd and goes to the opposite bus stop. commute bus.

Li Jiao was in the passenger seat of a commercial vehicle in the parking garage above the hospital, and his eyes followed Chen Jingqiu's figure until he disappeared into the bus.

"It seems that Chen Jingqiu is not interested in you at all." The person in the driver's seat said so.

Li Jiao pinched the tiger's mouth to bleed, and said expressionlessly: "Sheng Ming'an took my position. If he hadn't stepped in, the person Chen Jingqiu cares about now is me, and I will become the sun in his life. "

The person in the driver's seat sneered: "Bitch."

Li Jiao's face was gloomy, and the tiger's mouth was pinched even deeper.

The commercial vehicle started, and the street lights illuminated the driver's seat, revealing the face of the speaker. If Chen Jingqiu was here, he would definitely recognize him.

His half-brother, Chen Qingliu.

Chen Qingliu looks more like Chen Tianhe, with good features but not very brilliant. He is only 17 years old but looks tall and burly. He looks 25 or [-] years old. It is not a mature charm, a temperament that can be salty or sweet, but simply looks old .

His dark circles were heavy, his cheeks were sunken, it was obvious that his body had been hollowed out by wine.

In fact, Li Jiao has known Chen Qingliu for a long time. When he participated in the program "Young Strong" and was favored by Times Entertainment, Times wanted to sign him as an artist. At first, he only got in touch with him and was very optimistic about him, so he contacted the director at the time to make a show on the show. Break out, and finally push him to debut.

When the second episode of "Young Strong" was filming, Sheng Ming'an was also there, but Li Jiao didn't pay much attention to him. He knew what the director was up to, so he didn't pay much attention to Sheng Ming'an who was destined to be his stepping stone.

But he met Chen Jingqiu in the Children's Palace.

Since there were still fans at the scene, Li Jiao helped Chen Jingqiu. Unexpectedly, Sheng Mingan stepped in halfway to save Chen Jingqiu, and even spent 100 yuan to hire him away.

At that time, Li Jiao was a little puzzled and uncomfortable with Sheng Ming'an's actions, but because Sheng Ming'an and Chen Jingqiu were not in his eyes, he quickly put the matter aside.

Unexpectedly, in the past few days, Chen Qingliu contacted him and said straight to the point that he would let Times Entertainment sign him, give him resources, promote him to debut, and offered him a very generous condition. Chen Jingqiu's spiritual pillar.

In the end, Chen Qingliu himself came out and broke Chen Jingqiu's spiritual pillar with his own hands, hoping to drive him crazy in one fell swoop.

Li Jiao couldn't resist the temptation, so he did.

This is the main reason why Times Entertainment's agents and program directors maliciously bought Li Jiao from Hei Sheng Ming'an to praise Li Jiao, and Times Entertainment signed him and praised him afterwards.

At first, Li Jiao's contact with Chen Jingqiu was not very smooth, the other party was too defensive, his dark eyes seemed to be able to read people's hearts, and he was often frightened.

Until an opportunity came.

At that time, the only person Chen Jingqiu cared about was Aunt Yao, the maid who raised him. She wanted to be discharged from the hospital because she could not afford the medical expenses. Leave her and pay her medical expenses in advance.

He was only one step closer, but no matter how hard he tried in the future, he couldn't get closer to Chen Jingqiu. Instead, Sheng Mingan and Chen Jingqiu got closer and closer!

Li Jiao was flustered, but he couldn't take care of himself.

At this time, the business car drove to an unfamiliar square and stopped suddenly. The uncertain Chen Qingliu opened the car door and pulled Li Jiao down, kicking him to the ground: "Li Jiao, if you are not useful, I You've been destroyed long ago."

After finishing speaking, he looked at Li Jiao coldly for a while before driving away.

Li Jiao was trembling with fear. Last year, when Chen Jingqiu showed his face on the TV news because of the overturn of the Jinzhou viaduct, Chen Qingliu was so jealous that he hired a group of people to break Chen Jingqiu's leg.

Now Chen Jingqiu has not only been admitted to the University of Science and Technology, but also authored a paper in a top journal. He has become a pillar of society, and Chen Qingliu is even more jealous.

Whether he will lose his mind and do something crazy, Li Jiao can't imagine, but he must!We must find a way to get rid of Chen Qingliu!

besides!besides--

Sheng Mingan!

Li Jiao picked at the wound on the tiger's mouth as he walked, with a distorted and disgusted expression on his face.

It's all Sheng Ming'an's fault, it's all because he ruined himself!

And Chen Jingqiu, how could he go with Sheng Mingan?How could she speak for Sheng Ming'an? !

Obviously Chen Jingqiu was the one he met first, the first person he helped him, the first person who gave him warmth, why did he like Sheng Mingan? !

"—!"

Li Jiao suddenly stopped, his body stiffened, his pupils constricted, and his expression looked like he saw a ghost.

Do you like Sheng Mingan?Chen Jingqiu likes Sheng Mingan?The kind of love a man has for a woman?

That's right!It's the kind of love between men and women!

No wonder, he said that when Chen Jingqiu mentioned Sheng Ming'an, he behaved strangely, and his appearance was very familiar, as if he had seen him somewhere.

In the many romantic dramas he guest starred in, he has seen the same look countless times.

Do two guys like each other?Or Chen Jingqiu's unrequited love?

Chen Jingqiu likes Sheng Ming'an, does he like men?

So disgusting.

Li Jiao had a strange expression. Looking back at Chen Jingqiu whom he saw in the hospital just now, he had lost his youthful innocence and the gloomy and withdrawn past. Because of its excellent shape, it looks quite temperamental.

All in all, even if it is put into the entertainment industry, it will not be inferior to the face and figure of a celebrity who relies on his face to make a living.

Li Jiao changed from pinching the tiger's mouth to stroking, his mind was full of Chen Jingqiu, and if there was no Sheng Mingan, the person Chen Jingqiu would like would be him.

Seems like... not particularly bad.

***

The New Year's Day holiday was only three days away, so Chen Jingqiu and Sheng Ming'an couldn't stay in Jin City for long, so they took the time to do things.

Sheng Ming'an went to meet the team Chen Jingqiu was talking about, came to a small company named 'Blue River', and came into contact with the 'Leather Core' project.

Whether it was Blue River Company, Gexin Project or that team, including Lin Chengjian, the leader of the ic design team, Sheng Mingan had never heard of it in his previous life.

It should be that Blue River and the Gexin project did not survive the impact of the "core-making scam" and failed. Before that, "Seoul Hongxin" took away most of the investment funds, and then the 14nm euv was born next year. Flank attack, bankruptcy is a normal outcome.

As for Lin Chengjian, Sheng Mingan really didn't know, maybe he was still recruited by Chen Jingqiu, but he was not in the team of Blue River Company, nor was he in charge of the leather core project.

Chen Jingqiu introduced Lin Chengjian, and then introduced another person beside him: "His name is Lei Ke, the team leader in charge of lithography machine research and development."

Sheng Mingan looked at Lei Ke, he was a very ordinary young man, about 30 years old, and he was still wearing the dust-proof clothing from the laboratory.

"Hi, my name is Sheng Ming'an."

"I know you. You have developed an exawatt-level ultra-short laser solution and successfully modeled it. I have read your paper and am looking forward to your development of xfel light source, because I think xfel light source is the best way to replace extreme ultraviolet light source in the future. Jiayuan. My name is Lei Ke.”

Sheng Ming'an: "Heroes see the same thing."

Lei Ke's tense face immediately cracked open, showing a smile welcoming to our big family: "Are you free? Let's go to the laboratory to chat."

Sheng Mingan was moved: "The laboratory is here?"

Lei Ke: "Have you seen this building? Our company headquarters, although it is only five floors high, actually has four floors underground, all of which have been established as the Blue River Research Institute. In addition to being small in scale, it can be developed into a small semiconductor industry chain."

Sheng Mingan: "Amazing!"

Lei Ke is proud: "That's right! Let's go, don't waste time."

Lei Ke lobbied enthusiastically, and Sheng Mingan was full of interest. The two fell into the conversation as if no one else was there, and each spoke with bright eyes.

It wasn't until he stepped into the elevator that Sheng Ming'an remembered that he had forgotten about Chen Jingqiu.

Subconsciously, she turned to look for Chen Jingqiu, who waved helplessly: "Go and play. I'll go find you after I've dealt with the matter here."

Sheng Mingan's brows and eyes curved: "Mmm!"

Together with Lake, he went to the laboratory where the lithography machine was developed in the underground research institute to see the equipment, and get acquainted with the R&D team by the way.

While Chen Jingqiu went upstairs, Lin Chengjian followed him and said: "The news that we have purchased a 22nm process lithography machine has been released, and the order has increased, but the quantity of each order is not large. It should be a trial, and the bulk is still there." Watching."

22 and 20 nanometer lithography machines are the most advanced technology manufacturing today, and there is no one in China!

Now they have spoken to the outside world, only held a press conference, detailing the leather core plan and the newly purchased second-hand 22nm lithography machine. There is no video, and the working environment of the lithography machine is not open to the public, so the leading semiconductor industry in China is holding a wait-and-see attitude .

The small company placed an order first, and if Blue River delivered the goods on time, the industry leader would quickly follow up and transfer the investment funds that were originally optimistic about Hongxin to Gexin.

but--

Lin Chengjian: "I don't understand why you only let out rumors, but you don't open the lithography machine to the public for viewing and introduction. A simple thing has caused a lot of doubts."

After getting out of the elevator, a gust of cold wind blew in. Chen Jingqiu brushed aside the messy lock of black hair that covered her eyes and said, "Guess why Chen Tianhe invested in Hongxin?"

"Who?"

"Chen Tianhe, the boss of Tenghui Group, invested one billion US dollars."

"...He is particularly optimistic about Hongxin?" Lin Chengjian also hesitated.

"You don't believe it yourself."

Lin Chengjian spread his hands: "I don't know him well, maybe he has cerebral palsy."

"Injecting one billion US dollars is cerebral palsy in your eyes, but Chen Tianhe, who has been in the mall for many years, is not only not cerebral palsy, but also a smart person with ulterior motives." Chen Jingqiu pushed the door into the office and said, "A 64-bit quad-core CPU can make ?"

The CPU is the core chip, the central processing unit, and the 64-bit quad-core CPU process is 32 nanometers. In terms of functions, Intel's Core i7 is currently the best, followed by the Snapdragon 810 series released in the second half of this year.

Lin Chengjian: "It's almost there, but soon."

With the 22nm process lithography machine, production is not a problem, as long as they design the core CPU.

Chen Jingqiu responded and asked about other matters.

Lin Chengjian answered as soon as he could answer, and if he couldn't answer, he clapped his hands and said as if thinking of something: "There is a woman who has been calling you for the past few days, and her attitude is not very good. We intercepted her, and she said she was... uh , your mother."

Chen Jingqiu: "Li Yuhua?"

Lin Chengjian: "Yes! That's the name."

Chen Jingqiu: "She will call in the future, you just block the number."

For the purchase of a lithography machine, he took a lot of trouble to do a scene, starting from the mother-child relationship between him and Li Yuhua, to using Li Yuhua's husband, a Hong Kong congressman, and a senior executive of TSMC to get on Qualcomm, and finally In turn, the Qualcomm lithography machine pigeons were released.

However, due to the fact that the chip purchase channel proposed by Chen Jingqiu was too profitable, Qualcomm had to lower its stance and endure the anger of being teased. This does not mean that they will let the little people like TSMC and Li Yuhua go.

According to the gossip that Chen Jingqiu knew, Li Yuhua's congressman husband seemed to have taken bribes and stepped down, and was also restricted from entering the country.

After Li Yuhua found out that Chen Jingqi had tricked him, he frequently called the company to harass him. Once Lin Chengjian received a call, he was surprised that there were such vicious and disgusting words and curses in the world. black.

Only now did he realize that the cursing woman was really Chen Jingqiu's mother.

Lin Chengjian sighed secretly, the relationship between parents is like an enemy.

Chen Jingqiu murmured: "Money is not so easy to earn, right?"

Take 3000 million and just find someone to fool him, thinking he doesn't know?

In the basement research institute, Sheng Mingan put on protective clothing and walked in the spotless laboratory. There were dozens of staff members bowing their heads to work. Leike briefly introduced one or two of them with excellent technology, and the rest was about the research and development of lithography machines. .

"We are mainly divided into three groups to develop lens, engraving precision and exposure technology respectively. The light source part still adopts euv technology. We are applying for cooperation with Shenshi Institute of Optics and Mechanics. We also place our hopes on the development process of super-resolution lithography equipment of National Institute of Optoelectronics. Being able to speed up..."

In fact, it is impossible to complete the research and development of lithography machines by a single company. Therefore, in addition to raising a team, Blue River has also been working closely with national research institutes and some university research institutes.

The euv in Asmer, the Netherlands, gathers top technologies from European and American countries and more than 2000 scientific and technological talents. Every key technology reaches the peak of craftsmanship, and the craft parts of dozens of countries are gathered together to be manufactured, so euv is called the crown of craftsmanship. The brightest pearl, the acme of human craftsmanship, is never exaggerated.

The working principle of the lithography machine is to use a suitable laser light source to expose through a photomask with a pattern, and the pattern of the photomask is copied to a sheet coated with photoresist.

It is similar to taking pictures with a camera, except that lithography engraves the designed IC circuit on the wafer.

The key technologies of the lithography machine are the lens, light source, resolution and process node, etc. Others are not discussed. The lens alone uses German Zeiss from an old-fashioned optical instrument.

Germany's Zeiss, the world's top lens technology, is not one of them.

However, Zeiss adopts a non-sale and technology block policy for the lenses provided by Asmer lithography to China.

Sheng Mingan spent most of the day familiarizing himself with the laboratory and the team, understanding the current research and development progress of the Blue River team, and had a rough blueprint in mind.

On the other side, Chen Jingqiu received a text message on the way to the underground research institute.

The text message was sent by Li Jiao.

He said that Aunt Yao had a sudden emergency and needed surgery urgently, so if Chen Jingqiu was still in Jin City, he would go there quickly.

Chen Jingqiu called the hospital first, and after asking about it, she got the news that Aunt Yao was indeed in an emergency. She couldn't help frowning, and changed direction with her feet, and sent Sheng Mingan a WeChat message while walking towards the parking lot.

[Aunt Yao is seriously ill, I will go to the hospital first. ]

Sheng Ming'an's phone was not with him, and he didn't reply, Chen Jingqiu could probably guess it.

When he arrived at the parking lot, he opened the car door. Out of the corner of his eye, he caught a glimpse of a menacing figure. He subconsciously got into the car, pulled the door, and blocked the knife with a bang.

Chen Jingqiu looked up. The man who attacked him was wearing a black wool mask on his face. He was tall and tall. When he realized that he couldn't hit the target with a knife, he tried to open the car door to continue.

There was no weapon at hand in the car, Chen Jingqiu got out from the other side, with a strong figure, subdued the attacker by relying on his black boxing skills for several years, grabbed the knife, inserted his backhand into the back of the attacker's hand, pulled it out, and struck Without hesitation, extremely harsh.

The attacker screamed and kept backing away, staring at Chen Jingqiu in fear.

Isn't the young man in front of you talking about talent?Not a college student?

How can you be as ruthless as you are on the road? !

Chen Jingqiu shook the knife in his hand, blood dripped from the tip of the knife, he thought it was dirty, so he threw it away, and looked at the attacker: "Chen Qingliu hired you to kill me? He always does things without thinking. Cut off my leg, what do you want now? Cut off the hand or cut off the foot?"

The assailant trembled, his eyes suddenly stopped, and he fell behind Chen Jingqiu.

Chen Jingqiu seemed to be aware of it, and suddenly turned sideways and took a few steps to the side. This was originally one of the defensive methods, but he didn't expect that the opponent would not use conventional methods.

The new assailant raised a yellow-white bottle and sprayed white water mist on Chen Jingqiu's face. Chen Jingqiu, who was unprepared and inhaled a large amount of spray in one breath, changed his face, and soon became dizzy. He quickly turned around and ran away .

Before running far, Chen Jingqiu fell to the ground.
