Dragon Boat Festival, also known as Duanyang Festival, Dragon Boat Festival, Mid-Autumn Festival, Dragon Festival, Zhengyang Festival and Tianzhong Festival, is a traditional folk festival in China. Dragon Boat Festival originated from the worship of celestial phenomena and evolved from dragon festival in ancient times. On the Mid-Summer Dragon Boat Festival, black dragon spent seven nights in the sky, which was the day when the dragon flew, as the fifth poem in the Book of Changes, Gangua, said, "The flying dragon is in the sky". At noon, Long Xing was both "winning" and "getting right", which was a symbol of good luck. The origin of the Dragon Boat Festival covers the ancient astrological culture, humanistic philosophy and other aspects, and contains profound and rich cultural connotations. In the process of inheritance and development, a variety of folk customs have been mixed into one, and the content of festival customs is rich. Picking dragon boats and eating zongzi are two major customs of the Dragon Boat Festival, which have been passed down in China since ancient times and have never stopped.

Dragon Boat Festival, originally founded by the ancestors of the south, is a festival to worship the dragon ancestors. Legend has it that Qu Yuan, a poet of Chu State in the Warring States Period, jumped into the Miluo River on May 5 and committed suicide. Later, people also took the Dragon Boat Festival as a festival to commemorate Qu Yuan. There are also sayings in memory of Wu Zixu, Cao E and meson tui. Generally speaking, the Dragon Boat Festival originated from the ancient ancestors' choice of "Dragon Ascending to Heaven" as an auspicious day to worship the dragon ancestors, and it was injected with the seasonal fashion of "eliminating diseases and preventing epidemics" in summer. The Dragon Boat Festival was regarded as an "evil day of the moon" and originated in the northern Central Plains, with a memorial to Qu Yuan and other historical figures. The formation of Dragon Boat Festival custom can be said to be the product of the integration of North and South customs.

Dragon Boat Festival, Spring Festival, Tomb-Sweeping Day and Mid-Autumn Festival are also called the four traditional festivals in China.
