Wash the pot, dry it with a rag, then heat it, take a piece of fresh ginger and coat the bottom of the pot with a layer of ginger juice. After wiping, pour the oil into the pot. Once the oil is heated, you can put the fish in and fry it slowly. Or pour oil in a hot pot, and then put a spoonful of salt in the oil pot, so that it is not easy to break the skin when frying fish.
