Am Joshua, holder of a Ghanaian passport and a tourist in malaysia.

Joshua, it is possible. You need to apply for a tourist L visa, right? If yes, you need to provide your passport, the application form, a half-length color photo, your valid entry permit for Malaysia, hotel reservation, and flight itinerary. Besides, you may also need to provide an invitation letter from Chinese tourism bureau, and proof of your financial support.
And then submit the application to the CVASC to apply for it.
