Document required for my visit to Guangzhou.

For tour to Guangzhou, you are required following documents: the original passport; Visa Application Form of China; Invitation letter (if visit for the first time). If you cannot provide an invitation letter, then provide a visa recommendation letter from your employing company or organization instead; bank statements, round-trip air tickets booking. But if for business, additional invitation letters issued by the authorized government and the inviter company are required.
