Where's all the graff in this city!?
Beijing is probably the least painted city I've seen given its size and population, but if you look hard enough you can find some here and there. The reason being, I'm guessing, is strict vandalism laws and the fact that China has never experienced a major modern art movement like many other countries in the 20th century.
If you visit, be sure to check out the 798 District. It's a huge area of abandoned shipping/receiving warehouses that have been converted into chic art galleries and studios sometime after the Cultural Revolution of 1966. The art is almost purely Chinese, but I found a Spanish and Korean gallery as well.
