A box of frozen crabs was bought at spring festival, and there was still a big difference over fresh crabs. They were not evaporated. They had to be eaten, or they were to be melted. Family dinners, a big pot, salty, onions, good taste. I didn't expect to eat any more. Crabs are rich in proteins and trace elements and have a good effect on the body. Crabs are cold, salty, in the liver, in the stomach; they have thermal detoxification, graft, stomach digestion, heat spread, menstruation and blood break. There is some therapeutic effect on silting, yellow sluice, pain in the waist and rheumatism。
