The custom of eating mutton on the winter solstice is said to have started from the Han Dynasty. According to legend, Liu Bang, Emperor Gaozu, ate dog meat cooked by Fan Kuai on the winter solstice, which made him feel particularly delicious and full of praise. Eating dog meat on the winter solstice has spread among the people since then, not only eating dog meat, but also eating mutton and various tonics. I hope there will be a good sign in the coming year. Later, dog meat slowly turned into mutton, and it is best to match it with traditional Chinese medicine to dispel wind and prevent cold.

Therefore, the custom of eating mutton soup on the winter solstice is widely spread in Sichuan. On the winter solstice, people eat mutton and various nourishing foods one after another, in order to have a good omen for the coming year.

And it is the best season to eat mutton in the cold winter. In winter, the human body's yang is hidden in the body, so the body is prone to cold hands and feet and poor blood circulation. According to traditional Chinese medicine, mutton is sweet but not greasy, warm but not dry, and has the effects of tonifying kidney and strengthening yang, warming the middle warmer to dispel cold, warming qi and blood, stimulating appetite and strengthening the spleen. Therefore, eating mutton in winter can not only resist the cold, but also nourish the body, which is really a beautiful thing to kill two birds with one stone.
