Something regarding wild or controversial meats which I meant to mention, then forgot:
If you plan to visit China anytime, do not worry about accidentally ordering or being served something you'd never knowingly eat. Wild food, due to its legal status, is wildly expensive (pun intended). No one is going to serve you it as a cruel joke.
Dog, cat, horse and donkey restaurants proudly display the animals they are selling either in cages or in pictures.
