Because of China’s customary naming of food.

Pig stomach is called "pig belly", pig pancreas is called "Ye Tie" and "Hengli", pig tongue is called "pig profit", pig blood is called "pig red", and pig intestines are called "fat intestine".

Pig's feet are called "pig's trotters" and many other names.

If the above are mentioned, they are all called according to general medical or academic terms.

From now on, if you go to a restaurant and order "Cold Pork Stomach" or "Stir-fried Pork Stomach", it will only upset your "stomach".

Since it is regarded as food, it should be distinguished from other similar foods that should not be eaten, are not delicious, and should not be eaten, so as to avoid people's misunderstanding and people's psychological relief.
