Pig's trotters are a part of a pig's body. They are the feet of the pig, and they have bones and meat on them. They are sometimes eaten by people as food, but they need to be cooked first. Some people like to use them to make soup because they can add flavor and make it thicker. The meat on the pig's trotters can be tough, so cooking them for a long time makes them soft and easy to eat. Some people even like to eat the skin and fat on the pig's trotters because they give a nice flavor to the dish. Overall, pig's trotters are just like any other part of an animal that can be eaten as food, but they need to be cooked properly first.
