2. Wash the ribs and put them in the pot, add appropriate amount of water and a small amount of ginger slices and rock sugar (to avoid fishy smell), and cook for 5 minutes on high fire.
3. Drain the blood and impurities, remove them and put them in a bowl for later use.
4. Prepare a casserole (the casserole tastes particularly good when stewed, and diners who don't have a casserole at home can put it in the pot and cook it slowly).
5. Add an appropriate amount of water, add cooked ribs, ginger, garlic, green onions, star anise, fennel and pepper after boiling, and simmer for 2 hours.
6. After cooking for about 2 hours, add the chopped wax gourd (the side dishes here can be added at will according to your own preferences), and then simmer 15 minutes.
7. Put it in a bowl, and this home-cooked stewed pork bone soup will be presented to all diners.
