Is it possible to convert L (tourist) into Q1 (family) visa within China?

Hi, it is possible to convert L type into Q1 type within China. It’s worth a try. The required documents include your passport, the application form, a passport-style photo, valid registration form of temporary residence, an invitation letter from your wife/husband and copy of her/his Chinese ID card, as well as your marriage certificate, and other documents the consular officers consider necessary.
