If you are a student of Tsinghua Peking University, of course, there is no need to transfer to an ordinary undergraduate school in Taiwan Province, and the teaching staff can't compare with the key universities in Chinese mainland.
However, it is definitely a good thing for college and even higher vocational students to have the opportunity to receive the education from Taiwan Province in the past, understand the quality of local students and see the local customs (teachers are generally higher than similar schools in Chinese mainland). My friend has been to Jianguo University of Science and Technology, which is better than many ordinary undergraduate courses in China. The campus scenery is also very good, and the quality of students is generally high. If you have been educated in Taiwan Province Province, you will know that Taiwan Province Province is not what it is said on TV.
