1. It originates from the memory of Qu Yuan. According to the "Biographies of Qu Yuan and Jia Sheng" in the Historical Records, Qu Yuan was a minister of King Huai of Chu in the Spring and Autumn Period. He advocated to give merit and power, enrich the country and strengthen the army, and strongly advocated to unite Qi against Qin, but was strongly opposed by aristocrat Zi Lan and others. Qu Yuan was greedy to leave his post, and was expelled from the capital and exiled to the Yuan and Xiang River basins. In exile, he wrote immortal poems, such as Li Sao, Tianwen, Jiuge, which were concerned about the country and the people, and had a unique style and far-reaching influence (therefore, the Dragon Boat Festival is also known as the Poet Festival).
2. In 278 BC, the Qin army broke through the capital of Chu. Qu Yuan saw his motherland was invaded, and his heart was cut with a knife, but he could not bear to abandon his motherland. On May 5, after writing his final work Huaisha, he threw himself into the Miluo River with a stone and died, and wrote a magnificent patriotic movement with his own life.
