hello. i would like to ask the requirements of tourist visa in china.

Jandi, you need to prepare the following documents to apply for the tourist L type:
1. your passport and copies of its data page and the previous Chinese visa page
2. the completed application form affixed with a recently-taken passport-style photo
3. an invitation letetr from your fiancé
Personally, I don’t think your bank statement will be required.

Because you go there to get married, you should take the single status certificate with you.
