Donghai University is a private ordinary university located in Taichung City. There is a Lv Siyi church on campus, which is a famous scenic spot and one of the largest schools in private universities. The most prominent school is architectural design, which is the best major in private universities except biomedicine, so the design-related majors are very good.
National Taipei University of Technology and Yunlin University of Science and Technology are the top two or three technical and vocational colleges in China, and they are also quite good. National Taipei University of Technology is located in the center of Taipei, and the MRT (subway) is at the campus gate. The transportation is convenient, but the disadvantage is probably that the campus is small.
The campus planning of Yunlin University of Science and Technology is the best among technical and vocational colleges, and there is a design college, so many kinds of design majors are set up. However, compared with National Taipei University of Technology, the traffic is inconvenient and the excitement is far less than that of Taipei.
To tell the truth, all three schools are very good. Where did you go to see yourself? Generally speaking, the quality of students majoring in industrial design is slightly better than that of Donghai University, but National Taipei University of Technology will also attract good Taipei high school students, so I personally think it can be given priority.
You can consider Donghai or National Taipei University of Technology.
If you have any questions, you can also refer to the website of Taiwan Province Exchange Student Forum, which contains many exchange students' experiences. The website I repost often can't be displayed, please find it yourself.
