How can I apply for visa if I don,t know anyone in china

Majesty, maybe you can try to apply for a tourist L type entry permit for PRC to visit and buy some items. You can ask a travel agency to get the invitation letter for you and then prepare these documents including your passport and its copy, a completed application form attached with a passport-style photo, an introduction letter from yourself or your company, the invitation letter of a duly authorized unit, round trip air tickets and hotel reservation, as well as your recent 4-month bank statement. Afterwards, submit the application to the embassy of PRC to apply for the L type.
