I want a 6-month multiple f visa, what should I do?

Prepare the following materials first: a valid passport and its photocopy, a filled application for glued with a recently-taken color photo, an invitation letter or invitation confirmation letter from the duly authorized unit, an invitation letter from a relevant entity or individual in China, a guarantee letter from your company, and a bank statement of the latest six months.
