Black bean pig hoof soup

When I was a mother, I realized that being a mother was hard work, from pregnancy to raising a baby. Every mother is great, constantly giving for her children. And I made it for all the mothers of the world, and I hope you'll have a nice and healthy soup. This is a very high nutritional value, which is good food for mothers, with detoxification, pigmentation, kidney supplementation, milking, etc. The black beans in the soup are also called soybeans, odoury, rich in high proteins, vitamins, trace elements, and low in heat; and pigs' feet and feet are rich in gelatinic protein, which is good for beauty, and for some mothers who have four limbs that are tired during pregnancy and after childbirth, leg cramps, numbness, etc., have some therapeutic effect. The two food items are made together, and are nutritious and effective。
