As a matter of fact, Tsinghua University does not recruit adult undergraduates, so candidates can't apply for Tsinghua, whether they apply for the exam, take the self-taught exam or teach online.

Generally, the process of applying for undergraduate courses is in early September, and candidates register in the adult colleges and universities enrollment networks of various provinces or the education examination institutes of various provinces. Some provinces are on-site registration confirmation, and specific candidates know the application requirements of their own provinces.
