They led Yuanyuan back to his original home, an urban village with the word "demolish" everywhere, located in a quasi-regarded area and living in a low-income class.

Yuanyuan's house is on the third floor. The corridor is broken and dirty. There is no property or cleaning. There is even no trash cans around. The garbage bag needs to be carried far away and thrown away.

In addition, the quality of the people around him is slightly lower and the environment is even worse. Fang Han frowned. It is not strange that there is such a place in the beautiful Haitian City, but the strange thing is that no one has ever taken care of it. Maybe because it is about to be demolished, the government does not take action, and it will be closed with one eye. Therefore, no one cares about Yuanyuan and lets her, a little girl, fend for herself.

After Yuanyuan became Qi Hairong's daughter, it was no different from usual. Qi Hairong changed her studies for her, abandoned the past, and started again.

Yuanyuan entered Experimental Primary School, but her grades were not good enough and she couldn't keep up. Qi Hairong hired a tutor to provide her with tutoring and tried to keep up early.

Fang Han felt that Yuanyuan should be allowed to re-study the first grade to solve the problem of poor foundation. Besides, there is no loss in studying for one year late, and education is not that important for Yuanyuan.

Qi Hairong disagreed and insisted on letting Yuanyuan go back to the next level, and then finding the best teacher to give her some lessons, not only to make up for what is missing, but also what has not been learned, so that she can learn in advance.

Fang Han had no choice but to be Qi Hairong's daughter now, and there was no reason for him to take care of him. Zhang Tong had always lived at Qi Hairong's house and helped take care of Yuanyuan.

There are many things in Qi Hairong's company. I need to go over and see every day. The family is taken care of by Zhang Tong, Yuanyuan's things to go to school, writers who come back from school, etc.

Fang Han had no choice but to take Zhang Tong. She insisted not to let Fang Han see the doctor. Fang Han found an opportunity to touch her wrist. After seeing it, there was no problem.

It may be more psychological factors, not physiological reasons, and no matter how high his medical skills are, there is no way.

Since the divorce, Zhang Tong seems to have become much cheerful and relaxed, with a sweet smile on her face, which is kind and easy-going.

According to Fang Han's observation, she did not force her to smile. She was really liberated and relaxed, as if the Buddhist enlightenment had been enlightened, and she would cut off her worries from then on.

———

After dealing with these trivial matters, Fang Han came to school to continue classes. Even during these busy days, he did not forget to study and read the original math books listed by Gao Bo.

The original mathematics works are indeed different from mathematics textbooks. If you look closely, you can find the mathematician's way of thinking and thinking system. The great gains are by no means comparable to mathematics textbooks.

The substitute teacher in this math class was a teacher. He said in a deep mood that the original teacher Gao Bo had resigned. From today on, he would take this course by himself. I hope everyone can adapt. His thinking speed is not as fast as that of Teacher Gao Bo. Students can relax and don’t have to be so nervous.

Fang Han was stunned, frowned, resigned?

After class, he went straight to the detention center and saw Gao Bo. He had gained weight a little, his skin turned white. Obviously, his life here was very comfortable and his mood was very peaceful.

The two were talking in a small hut, and there was a policeman standing next to him. He closed his eyes slightly and seemed to have fallen asleep, obviously he had to explain.

"Teacher Gao, have you resigned?" Fang Han looked at him quietly.

Gao Bo nodded: "Well, I have resigned. Now that I'm so embarrassed to go back to teach students, and I'm not qualified to be a teacher."

"Yuanyuan has been adopted by Hairong, and it is a blessing in disguise. Teacher Gao, you have done what you shouldn't do, but it has not caused any harm. There is no need to feel so guilty."

"If you do something wrong, you will do something wrong. You cannot be unreproached because you have not caused terrible consequences."

"Then you don't have to resign." Fang Han said helplessly.

"I don't want to continue to stay at Southeast University, I want to change the environment." Gao Bo smiled bitterly: "It's just delaying you Fang Han."

Fang Han shook his head: "It's okay for me, where are you going, Teacher Gao?"

"I want to join my mentor Pocheyev." Gao Bo said: "The teacher has been inviting me to be his assistant in the past two years, and now I can finally agree."

Fang Han asked: "Mr. Gao is not going to come back?"

Gao Bo shook his head: "I'm sad and not going to touch this again, sorry, Fang Han."

Fang Han shook his head and said it was okay, frowned and said, "Then are you and Teacher Zhang..."

"I have nothing to do with Zhang Tong." Gao Bo shook his head and said, "Oh..., in fact, our original union was wrong."

Fang Han said: "What a pity."

Gao Bo smiled bitterly and sighed: "It's me that I'm sorry for her. My parents have bad personalities. Zhang Tong has suffered a lot of grievances. My husband is very unqualified. She can find her own happiness."

Fang Han sighed, "Why is this? Teacher Zhang is also very pitiful."

"She is the most pitiful." Gao Bo sighed: "I failed to take good care of her, which delayed her youth. I hope she won't blame me."

Fang Han said: "Teacher Zhang has friends here, so Teacher Gao doesn't have to worry."

"Qi Hairong?" Gao Bo smiled bitterly, "Qi Hairong is an amazing person. I have a headache when I see her. I don't know who dares to marry her in the future."

Fang Han coughed lightly and said embarrassedly: "Hairong and I..."

Gao Bo was stunned and then suddenly realized: "You and Qi Hairong...you two...?"

He gestured for a moment, his eyes widened in surprise.

Fang Han touched his jaw: "It can only be considered a good friend."

Gao Bo shook his head with emotion: "Fang Han, you are amazing!...Qi Hairong is not an ordinary woman. She is smart and powerful. If you want to be with her, you must be able to suppress her, otherwise you won't look at you with your eyes. She is too proud!"

Fang Han nodded: "She is such a person, but she is very kind."

"That's right." Gao Bo nodded and said, "She is very protective of Zhang Tong and scolds me whenever she meets. There is really nothing she can do, but with her by my side, I don't worry about Zhang Tong being bullied."

"It's really a pity for you two." Fang Han shook his head.

"The couple is like a fish drinking water, and you know the warmth and coldness." Gao Bo shook his head and said, "We should have ended it long ago. It shouldn't be delayed for so long. Fang Han, you have the opportunity to take good care of Zhang Tong in the future."

Fang Han nodded.

He left the detention center, drove back to Wanghai Garden, sat on the sofa and pondered, would Southeast University continue to study, and would he want to go to Princeton?

Southeast University has lost its high waves and its attractiveness has greatly reduced. He wants to have research results and to achieve success in mathematics, he needs a good tutor.

There are many good mathematicians in Princeton, especially game theory, who are at the top of the world, and digital game theory masters are there.

But he couldn't bear to live here. The environment of domestic universities is different from that of domestic ones. He likes the atmosphere here and studies here with a very calm mind.

While he was thinking, Yuanyuan came back from school. Before Qi Hairong and Zhang Tong got off work, she ran over and snuggled up to Fang Han, talking about the school affairs, which student was the most naughty, which student was the worst, and who wanted to bully him, but she ended up being dealt with by herself.
