3. add a proper amount of clear water to the pot, add ginger slices and scallions, boil them, put them in pig's hands, blanch them for about 2 minutes, and take them out for use.

4. Add 1 tablespoon salad oil to the pot and heat it. Add ginger and garlic and stir-fry for a while, then add dried red pepper and chopped green onion. Add pork knuckle and stir-fry for 2-3 minutes, then add boiling water. After that, add rock sugar (if you don't like the sticky feeling of the finished product, you can add less), star anise, fragrant leaves, soy sauce and carved flowers. Bring to a boil over high fire and simmer for 1 hour.

after 5 or 1 hour, when the soup is gradually thickened, add salt and a little white vinegar to medium heat, continue to burn for 3 minutes, and then turn off the heat, and stew for 2 hours.
