Tongzi bone is a traditional Chinese ingredient. It is also called pig tibia. It is composed of the tubular bones of the pig's front legs and hind legs. Tongzi bones are rich in nutrients such as collagen and calcium. They are delicious and chewy and are an important part of Chinese food culture.

Tongzi bones are popular on Chinese dinner tables, especially in winter, and can be cooked into a nutritious pork bone soup. Pork bone soup can replenish calcium, replenish qi, and nourish the body. It is especially suitable for people who are weak, have insufficient qi and blood, and often catch colds. During the stewing process, the tube bone can also play a role in removing the fishy smell and increasing the aroma.

In addition to pork bone soup, tube bones can also be used to make other delicacies. For example, you can grill the pork bone skewers into pork bone skewers and serve them with sauce, which will be full of aroma and endless aftertaste. You can also chop the tube bones into small pieces and add them to fried rice, noodles and other foods to increase the taste and nutrition. Tongzigu has a wide range of uses and is an integral part of Chinese food culture.
