There are two theories about eating mutton on June 6. One is that starting from the Yao and Shun period, eating mutton in summer can ensure the body's physical strength by attacking the heat; the other is that June 6 is the birth date of Western diseases, and eating mutton is the birth date of Western diseases.

Mutton and mutton soup can drive away diseases, so the saying of eating mutton on June 6 has been passed down to this day.

The historical origin of "Fu Sheep" on the sixth day of June in the lunar calendar belongs to the dog days of the sixth lunar month. Eating mutton during the dog days is commonly known as "Fu Sheep". There is a folk saying that "a bowl of soup for Sheep in summer does not require a doctor's prescription".

Fuyang Festival is a traditional Chinese food festival, which starts on the first day of Fuyang in the traditional lunar calendar every year and ends at the end of Fuyang, lasting for one month.

"Eating Fuyang in Futian" has a long history in Xiaoxian County, Anhui Province and Xuzhou, Jiangsu Province, which can be traced back to the Yao and Shun Dynasties.

Since ancient times, there has been a saying among the people in the Huaihai area that "a bowl of soup is enough for a sheep, and there is no need for a miracle doctor to prescribe it."

In the Xuhuai area, Xiao County is famous for its mutton. People in Xiao County, together with the Xuzhou area, have always had the custom of eating mutton during the dog days.

On the first day of each year, people are accustomed to buying mutton from the market and cooking it at home.

Since Xiao County was under the jurisdiction of Xuzhou in ancient times, there were frequent people-to-people exchanges between the two places. There were many restaurants in Xiao County that were opened in Xuzhou, which was also the reason why the festival was able to spread quickly in Xuzhou.

Xiaoxian mutton has enjoyed a good reputation for more than 300 years.
