other strange things
I also think some of China's misplaced reputation for weird food is that it is very much a head-to tail-cuisine. As are most other countries. Again, for China, this largely rises from food scarcities in the past and a culturally ingrained abhorrence of food waste. Waste not; not want.
So the butchers' stalls are going to have things that in the some western countries are only used in pet food, if at all.
Pigs are used from face
to feet
taking in their intestines part way. I've spared you the eyes.
Chickens are eaten from cocks' comb
to feet
taking in testicles in passing
Cattle are eaten not just for steak or other flesh cuts, but also the udders, penises and other parts the animals never knew they had are eaten.

This combines with a healthy lack of squeamishness and an easy acceptance that meat is from animals, unlike the plastic packed, anonymous looking meat in many western supermarkets, which bear as few signs of animal as possible.
I'm not posting these images to shock anyone, although I realise they may do some people, but rather to suggest that this is actually more normal than not. It isn't Chinese food that is weird; it is western food.
