Hello, Harbin Institute of Technology (Harbin Institute of Technology) is better in aerospace, machinery and electricity, but marine engineering and other marine-related majors seem to be inferior to the other three, and you should check that Harbin Institute of Technology seems to have no graduate students majoring in marine engineering, and they should all be related majors (maybe I am ignorant ~ ~). Dalian Maritime's marine engines should be the best, followed by Harbin Institute of Technology and Dalian Institute of Technology. But this only applies to professionals. The better the major, the more applicants and the greater the competition. But on the whole, 985 University is definitely the most difficult, followed by 2 1 1. As far as this major is concerned, the difficulty of these schools is not small, and it is really difficult to rank abruptly. Suggested references: Dalian Maritime University (School of Marine Engineering), Harbin Engineering University (School of Ship Engineering), Dalian University of Technology (School of Ship Engineering). Go to the forum to see if there is any previous experience. Also, you can Baidu about the major of "Marine Engineering", which will be systematically introduced and ranked by the school. . .
