First, you should determine your own direction. Tsinghua prefers casting, Harbin Institute of Technology and Tianda prefer welding. What you said about other schools is not clear. You can go to the websites of various schools to see if you are familiar with the direction, and then you have to look at your strength. I don't know Tsinghua. Tianda welding gets > every year. 340 points, Harbin Institute of Technology > 360-380. So you need to know your own strength and string. These two are first-class schools, such as Lanzhou Institute of Technology, Taiyuan Institute of Technology, North Institute of Technology, Jiang Institute of Technology and North Institute of Technology. Sometimes it doesn't have to be a prestigious school. You know, prestigious schools treat masters just like ordinary schools treat undergraduates. In their eyes, the focus is on cultivating doctoral students. So I can't learn anything at all. Of course, if you want to continue your studies, that's another matter. As for the information, I only have professional topics from a few years ago, and I will mail them to you if necessary. Just admitted to graduate school this year and worked for three years, which made me realize the importance of studying hard. I didn't choose a famous school, because I didn't have much energy to study because of my work, so I chose a second-rate school. Therefore, I have always stressed whether your position on yourself is commensurate with your ability. Finally, I wish you success.
