Wash the pot, dry it with a rag, then heat it, and then take a piece of fresh ginger and coat it with a layer of ginger juice on the bottom of the pot. After smearing, 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 pan, and then put a spoonful of salt in the oil pan, so that it is not easy to break the skin when frying fish.
