If you are a college entrance examination student or a parent, I will briefly say a few points for your reference, although I am not very familiar with these schools. First of all, Nankai belongs to a comprehensive university and was established earlier. The geographical location of Tianjin is still quite good. Although Nankai has been at a very stable level for nearly ten years, its arts and sciences are still relatively good. Tongji, in Shanghai, has a good geographical position and strength, but it is not necessarily better than that of that year. Tongji has always been a school with good civil engineering and strong engineering. Beihang University doesn't say much, but everyone knows where it is, and it's mainly universities of aeronautics and astronautics and universities of science and engineering. You certainly won't consider Beihang University. If you are interested in space flight, it is still a good choice. As for the Chinese University of Science and Technology, the scientific research strength of science and engineering is still very strong, and physical chemistry is not bad. Compared with the United States, it is the same as MIT in China. Yes, the Chinese University of Science and Technology is in Hefei, which is very sad in summer.
As for which is good, it depends on what major you study. The following are suggestions, whether to take it or not. If you are a college entrance examination party, the best way is not to come here to ask questions, choose your favorite major, and go to several schools in your mind to feel it for a few times, which is better than anything else. If you don't have time, ask the senior in person.
