The professional strength of Harbin Institute of Technology is the strongest (except Tsinghua, of course), followed by Tongji. The strength of the southeast is not the environment. So the best test is southeast. The most difficult test is Harbin Institute of Technology, which only breaks even after the initial test of 400, and there is no scholarship. Harbin Institute of Technology and Tongji University are both national universities, that is, they can find jobs anywhere after graduation, with strength and industry fame. In the southeast, maybe only in Nanjing, but Nanjing is also a good city. It's best to buy information about our school. It's safest.
