First of all, prepare the main ingredients, cut the meat thinner, and cut the potato hob smaller. Blanch the cut meat in water, turn on a small fire, take it out for later use, and drain it. Wash the pan clean, and don't let there be water in the pan, or you will splash yourself when you touch the oil. Heat the oil, add ginger slices and star anise, and stir-fry until fragrant. After about 30 seconds, pour the meat into the pot. Pour in the right amount of cooking wine. Stir-fry for a while, low heat, don't burn the meat. Then pour in cold water and drown the meat. Add a spoonful of soy sauce, less than half a porcelain spoon to consume oil, add onions, garlic, dried peppers and fragrant leaves. Cover the pot and simmer for 10 minutes. Lift the lid and have a look. Remember, don't burn the water dry, or the meat will burn off. If there is water shortage, water should be added.
