After this meal, Qiao Yu took Qiao Xi to play in Beijing for three days. Then Qiao Yu was informed that he couldn't return to Star City this summer vacation.
Because next, Tian Yanzhen invited Professor Zhang Yuantang from the University of California, Santa Barbara to give a lecture.
For Qiao Yu, who is determined to solve the Twin Prime Conjecture, this lecture is certainly not to be missed.
Besides, at the end of August, there is also a Natural Science Foundation research review meeting, which Tian Yanzhen hopes Qiao Yu can attend to broaden his experience.
Going home in this situation is just a waste of time. So going back, it could only be Qiao Xi and Xia Keke.
Elder Yuan asked Qiao Xi to report to Huaqing in mid-September.
Unlike Qiao Yu's situation, Qiao Xi might enroll in Huaqing through a 3+2+3 system.
So she needs to return to Star City to prepare a series of documents and corresponding evidence.
