I suggest you apply for Xiamen University. First of all, the environment is good. In the south, it may be difficult for children in the north to adapt to the south, but they really don't regret it. Besides, I'm from Heilongjiang. Harbin Institute of Technology not only accepts Tsinghua from Peking University, but also does not give any preferential treatment to Heilongjiang candidates. On the contrary, it is possible to improve the admission score of Harbin Institute of Technology because of these circumstances. Relatively speaking, the learning environment of Xiamen University is relatively comfortable, so Harbin Institute of Technology may be more bitter, with fierce competition and hard work. Also, if you are a girl, I suggest you take Xiamen University, where the ratio of male to female is relatively balanced. Finally, it depends on your favorite major, finance, ocean, Xiamen University and engineering. I hope my answer is helpful to you.
