Eating zongzi on the Dragon Boat Festival is now only known to commemorate the great poet Qu Yuan. According to legend, in 340 BC, Qu Yuan, a patriotic poet and doctor of Chu, faced the pain of national subjugation. On May 5th, he threw a big stone into Guluo River with grief and indignation. In order to prevent fish and shrimp from damaging his body, people throw rice into the river with bamboo tubes. In the future, people will put rice in bamboo tubes and throw it into the river to pay homage to Qu Yuan. This is the origin of China's earliest zongzi-"tube zongzi". Why did you wrap zongzi with wormwood leaves or reed leaves and lotus leaves later? There is such a record in the Elementary Book: During the Jianwu period of the Han Dynasty, Changsha people dreamed of a man who called himself Dr. San Lv (the official name of Qu Yuan) at night and said to him, "Everything you sacrificed was stolen by the dragon in the river. You can wrap them with mugwort leaves and tie the five-color silk thread later. Dragons are most afraid of these two things. " As a result, people made "corn millet" with "leaves wrapped in millet", which was passed down from generation to generation and gradually developed into the Dragon Boat Festival food in China.
