The people who live by the sea are so happy that they can eat fresh crabs and fish every day, and this is the recipe we made when Sanya drove to the port early in the morning, buying fresh fish shrimp crabs from fishermen who have just come out of the sea. 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。
