You can come to China with tourist visa (“L” visa), then apply for X visa after your arrival, but you are suggested to come to China with student visa (“X” visa) in case the university cannot help you change your tourist visa (“L” visa) to student visa (“X” visa)
Q: How do I get my student visa to China?
Once admitted, you will receive the university’s letter of admission and JW202 form. The applicant can apply for X visa at Chinese Embassy or Consulate General in your home country.
