There are many opinions about the origin of the Dragon Boat Festival, such as: in memory of Qu Yuan; In memory of Wu Zixu's theory; In memory of Cao E; From the three generations of summer solstice festival; The theory of exorcising evil days on the moon, the theory of national totem sacrifice in wuyue and so on. Each of the above has its own source. According to more than 100 ancient book records and expert archaeological research listed in Wen Yiduo's Dragon Boat Festival Examination and Dragon Boat Festival History Education.

The origin of Dragon Boat Festival is a totem festival held by Wuyue people in the ancient south of China, which is earlier than Qu Yuan. But for thousands of years, Qu Yuan's patriotic spirit and touching poems have been deeply rooted in people's hearts, so people "cherish it and mourn it, discuss it in the world and pass it on."

Therefore, the theory of commemorating Qu Yuan has the widest and deepest influence and occupies the mainstream position. In the field of folk culture, China people associate dragon boat racing and eating zongzi on the Dragon Boat Festival with commemorating Qu Yuan.
