According to folklore, "Fish is born on the solstice in winter, and dogs are born on the solstice in summer", but eating dog meat and lychee together on the solstice in summer is not as enthusiastic as usual. In Yulin area, there is a saying that eating dog meat can ward off evil spirits, strengthen the body and resist the plague from summer to sun. "Eat dogs from summer to day, and the west wind detours." The general idea is that as long as people eat dog meat in summer solstice, their bodies can resist the invasion of "west wind" and "bad rain", catch fewer colds and be healthy. Based on this beautiful wish, Yulin's unique folk food culture "dog meat from summer to day" has been realized. Especially in recent years, the local people have praised the saying that summer is the most abundant day for the sun, and eating litchi and dog meat, which are very "hot" (easy to get angry), just echoes the spirit of the sun, "controlling the sun with yang", so the "Dog Litchi Festival" adds fuel to the fire.
