When the chef sneezes, he basically doesn't turn his head, just spits it out of the pot and laughs and teases "add some ingredients." That chicken, frozen for nearly two months, has black bones, which is why you go to any wooden bucket meal to order diced Chili chicken, or fry chicken, and the chicken bones are black. And the chef will fry it, just to keep you from smelling it.
As long as the dead fish doesn't stink, I'll cook it for you if there is a refrigerator anyway. Even if the color turns red, it can't be seen when frying anyway. So try not to order braised fish pieces. As for pork, it is all inferior pork, and it is very likely to contain tapeworms. Beef is fake, and it is processed with other meat scraps mixed with beef essence.
Vegetables can be washed, but they won't be washed several times like at home, and they should be filtered with clear water. Just put it in the basket and rinse it under the tap.
