Choose a fish. After the fish is washed, cut a few knives evenly on the front and back to facilitate the taste. Put the onion and ginger slices into the fish belly, smear a little salt on the whole body, pour in cooking wine to remove the fishy smell, marinate for 20 minutes, stir fry the onion, ginger slices and dried red pepper in the oil pan, and pour the fish into the pan until the skin on both sides turns yellow. Add sugar, soy sauce, cooking wine and appropriate amount of water. Sprinkle chopped green onion or coriander leaves before cooking.
