Both schools belong to two engineering colleges in Tianjin. Actually, it should include tianjin polytechnic university. These three schools should be similar. The dominant disciplines of Tianjin University of Science and Technology are food, ocean and chemical industry. I'm not sure about the engineering university. It should be mechanical and electronic. In recent years, with the expansion and upgrading of colleges and universities, both science and engineering and HKUST are developing continuously, but there is still a long way to go, because I am from Tianjin. As far as my feeling is concerned, tianjin polytechnic university is a little better than Tianjin University of Science and Technology and Tianjin University of Technology. There are some differences in the characteristic professional fields between Polytechnic and Polytechnic, but there is no difference on the whole.
