Dragon Boat Festival, originally founded by ancient ancestors, is a festival to worship the ancestors of dragons and pray for evil spirits. It is said that Qu Yuan, a poet of Chu State in the Warring States Period, jumped into the Miluo River on May 5th 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 "flying dragons to heaven", worshiping the dragon ancestors on auspicious days, praying for evil spirits and injecting them into the summer season of "eliminating diseases and preventing epidemics"; The Dragon Boat Festival, regarded as "bad month and bad day", began in the northern part of the Central Plains and was attached to commemorate Qu Yuan and other historical figures.
