Raw materials: pig's head bone, carrot, iron stick yam, ginger, salt, candied dates, clear water and cooking wine.

Wash pig bones and cut them into small pieces. Put ginger slices and cooking wine into pig bones, and then remove and wash the blood foam. Put three and a half liters of water in the pot, add ginger slices, and then add pig's head bones.

Boil the water, skim off the foam and pour it into a large soup pot, then add carrots, yam and candied dates. After the fire boils, turn to low heat and cook for an hour, then add salt to taste, and you can go out!
