1. Buy back fresh chicken liver, soak it in water for more than two hours, change the water several times in the middle, and clean up the excess impurities and blood. In some places, blood needs to be cut with a knife to clean it up.
Clean up the chicken liver and put it in a pot with hot water for about five minutes. Wash it with warm water.
Put the water in the pot and boil, add chicken liver, onion, ginger, aniseed, cooking wine, soy sauce, salt, and simmer for 30 minutes.
Prepare the chicken liver with the soup until it is cool, then slice it or eat it directly.
