2. Heat the pan, add a little vegetable oil, add an star anise, then pour in the meat and stir-fry until the meat changes color.
3. Add onion ginger, soy sauce and thirteen spices, stir-fry until fragrant, then pour 1 tbsp cooking wine along the hot pot and stir-fry until fragrant.
4. Pour water, not too much meat, because no more water can be added during the whole stew. Cover the pot and bring to a boil. Simmer the meat for 30-40 minutes.
5. Add beans and season with salt. You can taste the soup a little salty, so that the stewed beans have a taste. Stir well.
6. Cover the pot and bring to a boil. Simmer for about 20 minutes until the beans are cooked and there is basically a little soup left. Don't leave too much soup, or the beans and meat will be stewed, and the rice will be delicious.
