"May 5 (lunar calendar), over the Dragon Boat Festival." The Dragon Boat Festival is a traditional festival of the Chinese nation. According to the "Continuation of Qi Harmonic Records" and "Jing Chu Years Chronicles", the Dragon Boat Festival after the Wei, Jin, Southern and Northern Dynasties was combined with the commemoration of Qu Yuan. By setting up altars to worship, swimming in the river, dragon boat races, zongzi sending affection, and "making late" in the township, this kind of folk custom has continued to this day in Qu Yuan's hometown and formed a tradition.
