I am renting a driver for a day in Beijing to go to the Great Wall, no tour guide. Solo traveler. The confirmation I received states the price does not include "meal and tips (optional)." In researching whether/how much to tip the driver, I am running into two conclusions:
a) no tip is required, or
b) drivers and tour guides for foreign tourists are the exception to the no tipping rule in China, they are underpaid because it is expected they will make money from tips. The recommended tip for the driver is 100+ yuan per person/day.
Is a or b the recommended option for respecting local norms? Thank you!!
