Why do you eat zongzi on Dragon Boat Festival to commemorate Qu Yuan? Hanging wormwood?

Every year on the Dragon Boat Festival on the fifth day of the fifth lunar month, there are customs of eating zongzi and racing dragon boats all over China. As we all know, this ancient custom handed down from generation to generation is to commemorate Qu Yuan. But why should we commemorate Qu Yuan in this way? It turns out that there is such an interesting story circulating in Qu Yuan's hometown. One night after Qu Yuan threw himself into the river, people in Qu Yuan's hometown suddenly dreamed that Qu Yuan was back. As before his death, his face was slightly sad and haggard. The villagers were so happy that they rushed forward to pay tribute to him. Qu Yuan replied with a smile: "Thank you for your kindness. Chu people love and hate clearly. If you don't forget me, I will die without regret. " Let's not talk about the old room. When they found that Qu Yuan's health was much worse than before, they asked with concern, "Dr. Qu, have you eaten the rice we sent you?" Thank you ",Qu Yuan was grateful at first, then sighed and said," What a pity. The rice you gave me was eaten by fish, shrimp, turtles and mussels. "Hearing this, the villagers were very anxious:" How can you not let fish and shrimp eat? Qu Yuan thought for a moment and said, "If rice is wrapped in bamboo leaves and made into corn with sharp corners, the aquarium will think it is water chestnut and dare not eat it. "In the second year of Dragon Boat Festival, the villagers wrapped a lot of corn with bamboo leaves and threw it into the river. However, after the Dragon Boat Festival, Qu Yuan said in his dream, "I ate a lot of corn you gave me, but many of it was taken away by the aquarium. "Everyone asked him again," What else can we do? " Qu Yuan said, "There is a way. Just put a dragon mark on the boat with corn. Because the Shui people were under the control of the Dragon King, they would beat drums, blow horns and turn oars at that time. They thought it was from the Dragon King and never dared to rob it again. "Corner millet, now is zongzi.
