Cut open the pork belly, clean the inner wall with clear water (you can rub it with salt and starch, and then wipe it with a clean rag), boil a pot of water with salt, fresh orange peel or lemon peel (as long as the outer layer needs it), cook the pork belly after the water boils, pick up the pork belly after the water boils again, clean it again, and scrape off the yellow part affected by bile with a knife. Slice. Stir-fry some black pepper and white pepper in a griddle and cook soup together. After the pork belly is cooked, you can pick it up, marinate it with soy sauce, cooking wine, sugar and pepper 1 hour, and add sesame oil, shredded ginger and soy sauce to serve. It can also be added to other parts of halogen.
