But he didn't make fun of their accents. In fact the last guy made fun of his.

If he had gone to "Actual China" very little would be different. Everybody who could speak English would be pushing each other out of the way to be friendly to the "foreign celebrity".

He wasn't making fun of anybody except possibly the two very elderly people who didn't speak English. Otherwise he was laughing with them not at them. Many people don't realize that Chinese are huge humorists and love teasing and mocking each other, often in a very nasty manner.

Oh come on. It wasn't racist at all. There was nothing in any of these scenes which were demeaning to Chinese in any way unless you consider it demeaning to point out that some very old Chinese don't speak English. Big deal.
