According to legend, in 278 BC, Qin Jun invaded Kyoto, Chu. Seeing that his motherland was invaded, Qu Yuan could not bear to abandon his motherland. On May 5th, after writing his masterpiece Huai Sha, he threw himself into the Miluo River.

After Qu Yuan jumped into the river, the local people rowed on the river in order to mourn, and later it gradually developed into a dragon boat race. People were afraid that fish in the river would eat his body, so they went home and threw rice balls into the river to prevent fish and shrimp from ruining Qu Yuan's body. Later, eating zongzi became a custom.

Dragon Boat Festival is to commemorate Wu Zixu.

The second legend of the Dragon Boat Festival is that May 5th is to commemorate Wu Zixu in the Spring and Autumn Period (770-476 BC). After Wu Zixu's death, Fu Cha was furious when he heard about it, so he wrapped Wu Zixu's body in leather and threw it into the river on May 5th. Therefore, it is said that the Dragon Boat Festival is also a day to commemorate Wu Zixu.

Dragon Boat Festival is to commemorate the filial daughter Cao E..

The third legend of the Dragon Boat Festival is to commemorate Cao E, the filial daughter of the Eastern Han Dynasty, who saved her drowning father. Cao E's father drowned in the river, and the body was not seen for several days. The filial daughter Cao E cried by the river day and night. 17 days later, he also threw himself into the river on May 5, and fished out his father's body five days later.

This was passed down as a myth, and then to the governor of the county government, who made it a monument for disciple Han Danchun to make a eulogy. Therefore, it is said that the Dragon Boat Festival is also a day to commemorate the filial daughter Cao E.

The Dragon Boat Festival originated from the totem festival of the ancient Yue nationality.

A large number of cultural relics unearthed in modern times and archaeological studies have confirmed that in the Neolithic age, there was a cultural relic with geometric prints and pottery ruins in the middle and lower reaches of the Yangtze River. According to experts' inference, the remaining clan is a clan that worships dragon totem, which was called Baiyue clan in history.

The decorative patterns and historical legends on unearthed pottery show that they have the custom of tattooing constantly, live in a water town and compare themselves to the descendants of dragons. Among its production tools, there are a large number of stone tools, as well as small bronzes such as shovels and chisels. As daily necessities, the printed pottery ding used for cooking food is unique to them and is one of the symbols of their ethnic group.

Until the Qin and Han Dynasties, there were still more than 100 Vietnamese people, and the Dragon Boat Festival was a festival for their ancestors. During thousands of years of historical development, most Baiyue people have integrated into the Han nationality, and the rest have evolved into many ethnic minorities in the south. Therefore, the Dragon Boat Festival has become a festival for the whole Chinese nation.
