Short visa holders (< 3 months), it is possible to get a provisional driver's license at the PEK airport or the transportation police stations in the city in minutes. You need to provide your passport as well as your foreign driver's license, and do a small examination(just to confirm you don't have physical or visual disability that effect the driving security), then you can get the provisional driver's license in minutes. With this license, you can legally drive cars in China. Ask any information desk at the airport for the direction of applying such a provisional driver's license.
