1. Put the bought sheep bones into a small pot, then rinse them with clear water, then add a proper amount of clear water to the pot and soak them in some cooking wine for one hour.

2. Take out the soaked sheep bones and put them on the chopping board. Knock the sheep bones directly with the back of the knife or the handle, but don't knock too hard. Just break the hole in the bone.

The purpose of this is to let the bone marrow flow out of the bones, take out the casserole used to make soup at home, and then add a proper amount of water to the casserole.

4. Cook the sheep bones a little first to make sure the blood is clean, then pour out the water for cooking the bones in the pot, and add a proper amount of water, which is better than the sheep bones.

5. Then add materials to the pot, cut ginger slices and green onions into onion segments and sprinkle them into the pot, then add a proper amount of cooking wine, sprinkle a few medlars, and first open a large fire to boil water.
