Put a little vegetable oil in the pot. When the oil is hot, put 2-3 spoonfuls of sugar in the pot. When the sugar is completely dissolved, immediately put the meat into the pot, stir fry constantly, and add soy sauce at the same time. When frying some oil, add boiling water to the pot and add seasonings such as onion, ginger, aniseed and salt. Never put cold water in it. After boiling, turn to low heat until the juice is thick.
