My second univ. in China. Education quality is best in engineering in China. Campus is 15th beautiful in the world. Dorms not good enough. International environment very good. Administration not good enough just like in China. Simply most popular university in China.
The best thing about Tsinghua is teaching quality and the contacts you may be able to make during your degree. I also found students and staff rather supportive and helpful. The worst thing I believe is the sometimes poor organisation and a lack of student activities
