Soak the dried fish in water for one day, for the following purposes: firstly, soak the excess salty taste; secondly, the soaked dried fish is easy to be cut into pieces and cleaned, because there is more dust on the surface of the dried fish after being exposed to the sun and wind. Next step of cooking fish: put onion, ginger, star anise and pepper frying pan in a hot pot, fry the fish pieces for about 3 minutes, add sugar, cooking wine and a small amount of braised soy sauce, then add one third of the peanuts in the fish pieces and add water to boil them with strong fire (peanuts are soaked in water for about 1 hour in advance), and then slow down with low fire.
