I have sent back dishes multiple times in China and gotten a new one with no problem and waiters are generally very nice (and not just to foreigners in tourist places). I guess waiters are different everywhere, restaurants are different and individual preferences are different.

are you sure those were real Chinese restaurants, not tourist trap restaurants? I was under the impression, from a local of China, that you could under No condition at all, request a dish be replaced. One chinese restaurant (a traditional one where the wait staff speak chinese) in the US wouldn't even do that.
