Hi and welcome to MCM
Your question has been asked multiple times, although the situation is quite fluid.
You will have to locate and enroll into an approved driver/rider course offered by an approved driving/riding school. The course will be provided/conducted in Mandarin... sounds like you may be comfortable with this. Various driver/rider schools have been discussed on threads/posts previously.

You may find some relevant threads in the Ride Prep & Making Tracks here to get you started. A few relevant threads including a 'sticky'

Another idea is to do a G00gle search with key words/terms and add mychinamoto into the search, this often provides better search results than using the MCM search engine

Post back what you find and how you manage to get on, especially given how fast things can change in the mainland
