Put it in water first, and pour some vegetable oil on the water. The mussels will stretch out to breathe hard and spit out the sediment. You change the water several times, repeat it several times, and put it for a few hours, and the sediment will be spit out. Of course, don't put too much vegetable oil, otherwise they will be suffocated and can't eat it.

Boil the shell with water, then take it out, fry it in oil, add onion, ginger and garlic, and finally add some soy sauce to eat.

You can also mash two eggs, add water, put them in mussels, onion, ginger and sesame oil, steam them together, and take them out after the whole bowl of eggs is solidified like jelly. This way of eating is delicious.

You can eat the whole meat inside.

As long as it is cooked well, it will not get sick, otherwise parasites and eggs have not been killed, which will easily lead to disease.
