In November, Yan Qing was very busy.

The main purpose of most domestic research scholars visiting American universities is to publish more articles and try to get their names on the articles.And these Yan Qing didn't care.

Bruno Manning's AI laboratory and Qiandu have a number of cooperative research and development projects, one of which is the research on autonomous driving technology.In autonomous driving technology, in order to drive safely, one of the most basic problems is to accurately perceive the lane structure in real time.

Yan Qing has been involved in the research of this technology, from the initial 2D lane line detection to 3D-LaneNet technology, Yan Qing has undertaken some of the core algorithm design.At the current stage, on the basis of 3D-LaneNet, the Gen-LaneNet method is upgraded and proposed, which is a general and scalable method for detecting 3D lane lines from a single image, which still requires a lot of testing and continuous debugging.

This year, Yan Qing had a lot to do. After Liu Cheng opened the topic, Yan Qing hardly had time to video chat with her, and because of the time difference, the communication between the two of them was much less.

Liu Cheng continued to read various literatures while replenishing knowledge, and the thesis progressed fairly smoothly.

At the end of November, the weather in Binhai was already very cold. Even though the library was well-heated, the space was too large for the students studying in the study room to wrap themselves in coats.

Liu Cheng read the book seriously, rubbing her hands from time to time.She was wearing Yan Qing's sweater, and the high collar held her neck warm.She likes to stick her nose to her collar, she always feels that the clothes are full of Yan Qing's smell.

In the afternoon of self-study, Liu Cheng would say a few words to Yan Qing from time to time, it was night in the Bay Area, Liu Cheng would sweetly say goodnight to Yan Qing, and urge her to go to bed.But she doesn't know that every "good night" is just the beginning of Yan Qing's night.

This day, Yan Qing continued with a cup of coffee as usual.

Coffee is something Yan Qing has never liked, whether it's instant, capsules, or hand poured, she doesn't distinguish between good and bad, she just uses it to refresh herself.Just like the Western food that Bruno invited her to eat, she will never be used to it. She said she has a Chinese stomach.

Yan Qing wanted to buy more time for the daytime tomorrow.

Tomorrow is Thanksgiving, and everyone in the lab is going to make big purchases. Yan Qing didn't want to join in the fun, but a few basketball-loving students said they were going to San Francisco Chase Arena to watch the Warriors' game, and Yan Qing was moved.

After so long, although Yan Qing can understand the rules of the basketball game, she still can't understand the NBA.She felt that everyone on the field was the same, and she could only distinguish different teams by their clothes. She couldn't recognize which star Liu Cheng mentioned at all.

Thinking of this, Yan Qing laughed, and she yawned, she was so sleepy that she was about to shed tears, but thinking about that child is also studying, although the two are at opposite ends of the earth, experiencing day and night respectively, but thinking about it, they are doing it. The same thing, still can't stop being happy.

There are many holidays in the second half of the year, and Christmas and New Year are approaching in December.

Yan Qing once said that Americans would take a few days off for the New Year, and she would come back if she had the chance.

This sentence seems to have become an agreement that the two did not agree on. The occasional videos of the two are full of restraint and patience, and they both hope to be fully released when that day comes.

In the name of helping Liu Cheng with her thesis, Fang Yu and Liu Cheng always get tired of being together, although Liu Cheng is often dragged away by Gu Shortan, but Liu Cheng is not easy to refute Fang Yu's face.

As long as he can stay with Liu Cheng, Fang Yu will be fine.

But Fang Yu is also very measured and never does anything out of line.After the post was published, Fang Yu just asked Liu Cheng a few questions, and didn't say any more.Liu Cheng thought, Fang Yu should understand.

At lunch time that day, Liu Cheng had just finished eating and walked to the dining table when the phone rang, and Aunt Song called.

Liu Cheng was very puzzled, Aunt Song never took the initiative to call Liu Cheng, Liu Cheng always called.

Fang Yu helped Liu Cheng take the plate from his hand, and Liu Cheng answered the phone.

Liu Cheng: "Aunt Song?"

"Chengcheng, I'm my aunt."

The caller was Aunt Song's younger sister, and Liu Cheng always called her Auntie.

Liu Cheng: "Auntie, it's you, have you returned to Yangliu Village?"

Auntie: "I didn't go back to the village, Chengcheng, my sister... she's very sick, she..."

Auntie's tone was crying, and Liu Cheng became anxious when she heard this.

"Auntie, don't cry, tell me quickly, what's wrong with Aunt Song! What's wrong with her!"

The tone of Liu Cheng's voice attracted many students in the cafeteria to wait and see. Fang Yu saw that Liu Cheng was very anxious and couldn't control his emotions. It seemed that he couldn't eat anymore in the cafeteria. He simply packed the food and dragged Liu Cheng out. canteen.

Auntie just cried, crying until Liu Cheng became even more anxious. "Auntie, don't cry, don't cry, you talk, Auntie!"

The two cried for a few minutes, and the aunt gradually stabilized her emotions.

Aunt: "My sister has had blood in her stools for the past six months. She didn't take it seriously. She bought some hemorrhoid medicine, and it got better. A while ago, she had stomach pains from time to time, but she didn't take it seriously. Later, her stomach hurts really. No, go to the county for an examination, the county hospital said..."

Speaking of this, my aunt choked up again.

Liu Cheng stomped her feet anxiously: "Auntie, what did the hospital say? What's the problem? Tell me, Auntie!"

Aunt: "The doctor in the county said it was cancer and needed surgery."

Following the aunt's sobs, Liu Cheng was completely stunned while holding the phone.

How could it be cancer?Aunt Song is usually in good health.Liu Cheng's mind was in a mess.

Liu Cheng squatted down, trying to restore her thinking to normal.

Operation?Is that okay?

Liu Cheng patted her face to calm herself down.

"Auntie." Liu Cheng called out. "The doctor said surgery, can surgery cure it?"

Aunt Song gradually stopped crying: "It seems possible. The doctor said to remove it. It should be fine after a few years, but it seems that you have to bring a feces bag."

Liu Cheng gradually stabilized.

"Auntie, which hospital is Aunt Song in? I'll ask for leave to go back."

"Chengcheng, you... Are you nervous about studying? I don't think it's okay not to tell you, but if you are too nervous about studying, don't come back."

"It's okay, auntie, I will arrange a time, and you tell me the address."

After talking on the phone with Aunt Song, Liu Cheng sat on the steps at the entrance of the cafeteria with a heavy heart.

Fang Yu sat quietly beside her, watching Liu Cheng with her head hanging between her knees, tears dripping down on the frozen ground.Fang Yu raised his hand, hesitated for a while, and finally hugged Liu Cheng.

This time Liu Cheng was a little listless in the video, after a few words, Yan Qing noticed that she was in a different mood than usual.

Yan Qing: "Chengcheng, do you have something on your mind?"

Liu Cheng moved her mouth, but didn't make a sound.Yan Qing saw it and knew it wasn't a network problem, so she waited slowly for Liu Cheng to continue.

Liu Cheng sighed: "Teacher..."

Liu Cheng stopped again, she put her phone on the table, and put her hands on her temples, looking very tangled.

Yan Qing: "Tell me what's going on, let's face it together, okay?"

Liu Cheng lowered her head, then raised it slowly, looking at the screen.

"Teacher, Aunt Song... is ill and needs an operation. I want to ask for leave to take care of her for a while."

"Aunt Song? What's wrong with her? What's the disease?" Hearing Liu Cheng's words and Liu Cheng's troubled expression before, Yan Qing felt that the matter was serious.

"Now the diagnosis is colon cancer, and surgery is still possible."

Yan Qing's expression froze for a moment, and she pondered for a while: "Colon cancer, if you can still be operated on, the cure rate is quite high. But then you have to go back for a long time."

Liu Cheng: "Well, at least accompany Aunt Song to finish the operation, and wait for her to get better."

Yan Qing nodded.

"How about I go back with you." Yan Qing said quietly.

Liu Cheng: "Ah? How can this work!"

Yan Qing frowned, this idea really didn't work.Before, she thought about going back for a few days during the Christmas and New Year's holidays, and it would be fine to go for a few days, but it may take a long time for Liu Cheng to go back this time, and she really can't go for that long on her side.

Liu Cheng saw what Yan Qing was thinking.

Liu Cheng: "Teacher, I really don't need to bother you, I will take care of it."

After this call, both of them were dull for a long time.

The New Year's meeting turned into a bubble, and at the same time, Liu Cheng asked for leave to suspend the progress of the thesis.

Yan Qing didn't sleep well that night, thinking about many things.

Lying on the bed, Yan Qing looked out the window, the night sky in California was beautiful, but she felt that she was far away from Liucheng.

She could think of Liu Cheng's helplessness when she knew that Aunt Song was ill, her thin shoulders twitched and her eyes red from crying when she cried, but she couldn't help anything, she couldn't even give her a hug by her side .Say something to face together, but Liu Cheng is left to face things alone.

Yan Qing closed her eyes, tears wet the pillow.

The dissertation had just passed the stage of opening the topic, and just recovered, Liu Cheng encountered such a thing again, and had to ask for leave to go back, Zhou Shuling thought about it, and still gave the leave.

Seeing Liu Cheng's heavy back leaving the laboratory after thanking her, Zhou Shuling couldn't help shaking her head, alas, this child is really pitiful.

Zhou Shuling was a little helpless, she had to apologize to Yan Qing, after such a toss, if Liu Cheng's graduation thesis could be completed on time, that would be the best result.If Liu Cheng postponed her graduation and she didn't take care of the child Yan Qing entrusted to her, how could she explain it.

Thinking of this, the old lady sighed, put on her glasses and picked up the phone.

Back in the dormitory, Liu Cheng simply packed up his luggage. Gu Shortan wanted to help, but he couldn't do anything, so he sat quietly by the side and watched Liu Cheng pack his things.

Usually, she was used to seeing Gu Shortan making noises, but this time she was sitting so quietly, Liu Cheng was not used to it.

Liu Cheng tilted her head and looked at Gu Duan and smiled: "I'm fine, I'll just go back and stay for a while, and I'll be back soon."

Gu Shuan pursed his mouth and said nothing.

She knows that Liu Cheng's family is not well off, so she usually listens to what Liu Cheng tells her, and she doesn't ask what Liu Cheng doesn't want to say, and she never deliberately takes special care of Liu Cheng. Orange is held in great esteem.

After the post was published, except for the short-term surprise when I first found out, I completely entered the state of "protecting Fang Yanqing" and "protecting Fang Liucheng".

In Gu Short's own words: My sister can tell right from wrong!

But now, "Sister Carrying Qing" is sitting beside Liu Cheng in a well-behaved manner.

Hearing Liu Cheng's simple words, Gu Shortan knew that Liu Cheng might not be able to return until many years later.

Liu Cheng doesn't have many things, and the clothes she often wears are stuffed in her bag, and the rest are books.

While tidying up here, the phone on the table rang.

Liu Cheng was startled, recently she received the most calls from her aunt, which made her anxious and sad every time.I'm a bit terrified of the phone ringing these days.

The phone was from an unknown number, Liu Cheng picked it up, and asked softly: "Hi, hello, may I ask..."

"Hey, it's Liu Cheng, right? I'm Yan Qing's mother~" The kind voice came from the microphone.

After Yan Qing went abroad, Liu Cheng never had any contact with Yan's mother. When she received Yan's mother's call, Liu Cheng felt guilty.

Liu Cheng: "Hello, Auntie, I'm Liu Cheng, hello."

Mama Yan: "Hey, little Liucheng, long time no see. I'm downstairs in your dormitory. You live in No. 5 dormitory. I'm in... This is the west gate, yes, the west gate of No. 5 building."

Liu Cheng was startled: "Auntie, I'll come down right away, you wait inside the door, it's cold outside, I, I'll come down right away." Saying that, she was about to rush out the door.

"Chengcheng, coat!" Gu Shortan grabbed Liu Cheng's coat and threw it to her.

When she was about to run to the west gate, Liu Cheng saw Yan's mother standing by the door wearing a thick coat from the stairs.For the first time, Liu Cheng found out that Yan Mama and Yan Qingniang actually look alike, they both have such kind eyes, a smile at the corner of their mouth, and a calm demeanor.Liu Cheng felt a little sore in her nose, she really missed Yan Qing.

Liu Cheng ran to the door in a few steps. A student opened the door and brought the cold wind in, but she didn't feel it.

"Slow down, you child, it's so cold, just put on a coat, ha ha." Mother Yan watched Liu Cheng running down in a hurry, and said with a smile.

Liu Cheng: "Auntie, hello Auntie! You... why are you here?"

Yan's mother shook the things in her hand: "Qingqing said that you have something to do at home and you have to go back for a while. This is her laptop. She said let me bring it to you. You can use it. You are about to graduate, and you have to go home for a while. I have to take care of it, and I'm afraid you'll throw away your studies." With that said, Mama Yan handed over the computer.

Liu Cheng looked at the computer bag in Yan's mother's hand, and the soreness in her nose just now came out all of a sudden.

Yan's mother blinked, and with the other hand, she took out a handkerchief from her pocket and handed it to Liu Cheng.

"Hey, it seems that Qingqing is right. She said that you are a little crying bag. You must cry when I give you a computer. I still don't believe it. Here, she asked me to give you a handkerchief, hehehehe."

Hearing what Yan's mother said, Liu Cheng took the handkerchief and smiled embarrassedly with tears in her eyes.
