1 The fifth day of the fifth lunar month is the traditional Dragon Boat Festival in China. According to legend, during the Warring States period, Chu and Qin fought for hegemony, and the poet Qu Yuan was highly valued by the King of Chu. However, Qu Yuan's thought was opposed by the old school headed by Shangguan doctor Jin Shang, who slandered Qu Yuan in front of Chu Huaiwang. Chu Huaiwang gradually alienated Qu Yuan, and the ambitious Qu Yuan was deeply saddened. He wrote immortal poems with uncontrollable melancholy and anger, such as Li Sao and Tian Wen.

2. In 229 BC, the State of Qin occupied eight cities of Chu, and then sent messengers to invite Chu Huaiwang to discuss peace with the State of Qin. Qu yuan saw through the plot of the king of Qin and risked his life to enter the palace to state his thoughts. Chu Huaiwang didn't listen and attended as scheduled. He was imprisoned as soon as he arrived in Qin. Chu Huaiwang is depressed and ill. Three years later, he died in the state of Qin.

3. Shortly after Chu Qingshuai ascended the throne, the king of Qin sent troops to attack Chu. Qing Shuai retreated from the capital in a panic, and Chi occupied Yingcheng. On the way to exile, Qu Yuan heard the bad news of Yingcheng's defeat. He lost all hope, sighed and jumped into the Guluo River. Fishermen on the river and people on the shore heard that Dr. Qu Yuan drowned in the river. They all came to the river to salvage Qu Yuan's body. People take zongzi and eggs from home and throw them into the river. If the fish ate them, they wouldn't bite Qu Yuan's body. Another doctor poured realgar wine into the river, so that the dragon and the animals in the water could be anesthetized and Dr. Qu Yuan's body would not be hurt. Since then, on the fifth day of May every year, Chu people row dragon boats, throw zongzi and drink realgar wine on the river to commemorate the poet, and the custom of Dragon Boat Festival has been handed down.
