After arriving, the driver brought the gift and drove away. Zhang Kun and Tang Jianyu walked too far through the hall under the greeting of Brother Du, listened to the hot greeting of Master Du's mother, and came to the living room. The little birthday star was lying next to Du Lao, and the grandfather and grandson were interestingly untying the Luban lock brought back by the little aunt, and when they saw Tang Jianyu, they got carried away, and their little mouth was full of joy, and they left their grandfather and screamed and pounced, "Wow, Uncle Tang!" Tang Jianyu smiled and held the little girl's round face to stop her from throwing herself into his arms.

When Du Lao saw the two beloved apprentices, he waved his hand happily, and Tang Jianyu pulled Xiao Shouxing and Zhang Kun to the teacher's side to say hello. "Quick, sit down!" Du Lao tidied up the coffee table and pouted at the two juniors. Zhang Kun gently pressed Du Lao's shoulder, quickly searched for the books on the table with his empty hand, and said, "Sit, me and Jianyu, what are you polite about." Du Lao listened comfortably, leaned back on the sofa with peace of mind, and briefly asked the two of them about the situation on the road.

Brother Du brought a drink and said, "You don't need to entertain, let's chat with my dad first." I don't have time right now, I'm going to get the drinks right away, and my mom and sister have to prepare them with the cook. Zhang Kun put the toys and books packed on the coffee table on the shelf not far away, sat back next to Tang Jianyu, and said, "I haven't seen you for a few years, big brother, you will socialize!" Brother Du was speechless for a while, and replied: "Zhang Kun, you are really!" The little birthday star called out sweetly: "Dad, hurry up, otherwise what if everyone has no wine at my birthday party for a while?" "I can't help but laugh.

"Then you know it's your birthday, do you want to go with your dad?" Brother Du teased his daughter, and the little birthday star put his arm around Tang Jianyu, put his little head against his elbow, and said resolutely: "I'm not going, I want to accompany Uncle Tang!" Hearing Tang Jianyu laughing loudly, Brother Du shook his index finger at his daughter and said to Zhang Kun: "Jianyu, no matter how old or young, recruits girls wherever he goes!" It's really a hell of a life when you look at it, I haven't seen him a few times since I was a child, and I'm still sticking to him! ”

"Probably because he spent time in elementary school, he has the familiar feeling of a child." Zhang Kun sat leisurely, with one hand under his nose, looking at Tang Jianyu with a smile. Du Lao's eyes lit up, as if he had been confused by a puzzle that he couldn't figure out, and said in surprise: "Ah Kun makes sense, maybe it's true!" Everyone laughed, Zhang Kun lowered his eyes and looked at Tang Jianyu, Tang Jianyu just looked at the palm of the hand that was broken by the little birthday star, and did not answer.

Du Lao is a professor of mathematics, Mrs. Du worked in the life school of the university before retirement, is a biology expert, their eldest son and daughter-in-law are fluid physics researchers, including the youngest daughter who arrived home after a while and the second son who settled in other places, are all practitioners of higher education, a family of scholars, do not pay attention to false socialization, but pay more attention to the cohesion of the family, so the tenth birthday of the little birthday star only has a family, and the other is like Tang and Zhang, people who have a close relationship and a coincidence.

"Ah, I'm back, this isn't the Prince Charming of my youth, Brother Zhang Kun!" As soon as Du Lao's youngest daughter entered the door, she screamed loudly before she put down her luggage. When he was in college, Zhang Kun often went to Du's hometown in the faculty compound, and the most unbearable thing was this junior sister who was twittering for herself, but she didn't expect that now everyone is forty years away, and she is still as enthusiastic as her girlhood.

The corners of Zhang Kun's mouth moved, and he said, "What's the matter, didn't my brother-in-law come back?" Du Xiaomei pouted, "He can't spare time." Saying that, he called "Dad" and his eyes fell on Tang Jianyu, because when Tang Jianyu was in Du Lao's hands, she had already gone to study in other places, so she was not familiar with each other, and asked tentatively: "Is this ...... Is Jianyu a younger brother? Tang Jianyu stood up and said hello with a "hmm". Du Xiaomei tilted her head and smiled, looked at her father and said, "I can see it, my father takes students, not only to look at the grades!" ”

Du Lao has always liked the lively little daughter, so he couldn't help but smile and asked, "What else are you watching?" Du Xiaomei Nunu mouthed, "Do you still need me to say?" Isn't it just about looks! "Haha! Look at her! Du Lao looked at the two students, pointed to his daughter and shook his hand, and said, "Don't play tricks, put your things away and go to see your mother, it's time to find fault with you in a while!" Du Xiaomei held up her small travel bag and greeted her, "You guys sit, I'll go over and have a look first." ”

The dishes are ready to stop, and the people are also ready to take their seats after Brother Du takes the wine and takes his wife back, and they can be served! "It's all the family who don't pay attention to it, just sit down!" Mrs. Du pulled Tang Jianyu, looked at Zhang Kun again, and urged the two of them to sit down quickly. After the banquet was full, Brother Du said some polite words before the banquet on behalf of Du Lao, and asked today's protagonist, Xiao Shouxing, to perform a show for himself, the ten-year-old girl was so embarrassed that she actually memorized a "Red Cliff Fu", which made Brother Du laugh, "Our family's literary cells are probably focused on you!" ”

This is a group of people who rarely have the opportunity to get together and eat a meal even if they are affectionate, so they naturally eat and drink aside, and the narrative is the "main meal", at first Brother Du talked about a modern communication project in their research institute, and there are problems that cannot be tackled for a long time, "If you can't get the results, the funding application will become a problem, and the lack of funding will make the follow-up research even worse!" Brother Du put down his chopsticks, his eyes fell on Zhang Kun, and said: "Ah Kun, you are an entrepreneur and understand scientific research, why don't you invest more in these projects!" Zhang Kun knew that Brother Du was just teasing, put down the wine cup and smiled: "You really have to pay attention." ”

Du Lao didn't hear it, but reflexively spoke for Zhang Kun, "Are those projects invested if you want to?" If you only engage in research, you don't know how much work it will take for them to review a topic! Brother Du was unimpressed by the old man's occasional partiality, and said with a smile: "The old man still thinks about it more!" Du Lao looked at Tang Jianyu and asked, "Ah Yu, you have a textbook compilation project on hand now, right?" Tang Jianyu put a water chestnut in sugar water into the bowl of the little birthday star, and replied: "This is the big project." Du Lao nodded with satisfaction, "This is a major event for the benefit of the country and the people, we must go all out!" ”

Tang Jianyu nodded yes, Zhang Kun raised his eyebrows, turned his head and said: "You are better than me, as Du Lao wished, you have taken root in the mathematical circle." "That's all I know." Tang Jianyu waved his hand again and again and said, "Brother Du, you have wronged him, he has already invested in an AI project, and the branch is in the incubation base of the development zone." The Du family was quite surprised when they heard it, and asked a few more questions, Zhang Kun did not hide it, and introduced the current basic situation of the technology company, including the change of equity, "Professional things are still left to professional people to do." ”

Old Du thought for a while, and suddenly patted Mrs. Du's shoulder and said, "I remembered, it's really a coincidence!" Zhang Kun and Tang Jianyu cast curious glances together, Du Lao looked around, and said: "Listening to the name of Ah Kun's company, I think of it, my mother and I asked their person in charge to send it back once!" As he spoke, he pointed to his eldest son and said, "It's when you go to the hospital again on vacation, and let the two of us go back from the University for the Elderly!" ”

Brother Du finally thought about it, and hurriedly asked what was going on, Du Lao and Mrs. Du, you glanced at me and talked about Shi Jiaojiao and Tian Hao picking them up that day. Mrs. Du was deeply impressed by Shi Jiaojiao, and her words revealed some affection, "Ah Kun, let me tell you, the little girl in charge is very good, she treats people generously, is not humble or arrogant, and when she deals with people, she is very calm, I can't help but praise her!" In a word, the eyes of the two men at the table flashed.
