According to relevant records, in the Warring States period, Qin Degong ascended the throne the following year, and it was very hot in June, and the plague was prevalent. Qin Degong ordered his subjects to kill dogs to ward off evil spirits according to the saying that dogs are yang animals, which later formed the custom of killing dogs in the summer solstice. "Eat the dog on the summer solstice, and the west wind will take a detour", which means that when people eat dog meat on the summer solstice, their bodies will be able to resist the invasion of the west wind and rain, catch fewer colds and be in good health. It is based on this good wish that the unique folk food culture of "dog meat on the summer solstice" has been achieved.
