How can get a tourist visa to nantong china? If i have an invitation letter from my fiancee?

Lorna, it’s almost impossible for you to get a tourist L type with the stay duration for 3 months. But after your entry, maybe you can apply for an extension before it expires.
The first thing is to prepare those documents including your passport and copy of its data page, the completed application form attached with a recently-taken passport-sized color photo, and the invitation letter from your fiancée. You may also be required to provide the proof of the financial support. You can use your fiancée’s bank savings account as your financial your.
Next, submit your application to the embassy of PRC in Philippines to apply for it.
