A piece of tenderloin or use plain lean meat will do. Wash the meat, cut it into small pieces and put it into a pressure cooker. Put in the appropriate amount of ginger, garlic, cooking wine, salt, soy sauce, star anise. Pour in a little water, a little bit will do. Press the meat twice in the pressure cooker and pour it out, keep the soup. Fish out the star anise, garlic and ginger and throw them away. Pour a little oil into the frying pan and grease the pan well. Reduce the heat to a gentle simmer and pour the meat into the pan. Use a spatula to flatten and crush the meat and stir-fry. While stir-frying, pour in the gravy and stir-fry slowly over low heat. Evaporate the water from the meat loaf. Stir fry until you look very fluffy look on the line.
