Fuyang is the mutton after squatting. Every year from the beginning to the end, China's Xuzhou, Jiangsu and other places will hold Fuyang Cultural Festival for more than a month, and local people will hold a grand ceremony to drink mutton soup and eat mutton. This custom also has a long history. It is said that it originated in the Yao and Shun period and has been circulating for a long time.

Eating mutton while sleeping follows the principle of "nourishing heat with heat". Mutton is a warm food. In summer, drinking a bowl of hot mutton soup will make you sweat instantly. People think that this process can not only dissipate heat, but also take away the moisture and cold in your body and let your body excrete toxins.
