Talha, if you visit for sightseeing purpose, you need to submit your passport, a copy of the data page of your passport, a completely filled application form affixed with a passport-sized photo, round-trip tickets and hotel bookings, the original and photocopy of your residence permit in Saudi Arabia, and perhaps an invitation letter from the duly authorized unit. The last document should be obtained from the China Tourism Bureau via a qualified travel agency if it is required.
