1, as a blessing
Dragon Boat Festival is a time when spring is cold and summer is hot, so we should pay attention to everything. In ancient times, people thought that diseases were brought by ghosts, so during the Dragon Boat Festival, people would make a pile of calamus, wormwood and garlic and hang it in front of the door, hoping to avoid snakes, insects, ants, monsters and ghosts. On the Dragon Boat Festival, children put mugwort leaves in their ears, wear calamus on their heads and write a "king" on their foreheads with realgar wine.
Scare away evil spirits.
2. Myths and legends
It is said that there was a monster in ancient times, whose tongue turned into a bridge, deceiving people into believing that it was a flyover and could become an immortal. People believed it and finally got into the stomach of a snake. Zhao, a local artist, dreamed that Taibai Venus taught him to kill Mang with a bow and let ordinary people hang calamus and wormwood in every household to avoid snake venom. Later, he successfully defeated the snake, but the snake was poisoned by wormwood and calamus.
3. Historical legends
In order to stabilize people's hearts, the Huang Chao Uprising Army sent a counselor to tell a woman that the refugees could break Huang Chao's knife by planting wormwood at their doorstep. This woman is very kind and persuaded many people. They planted wormwood at home and didn't run away because of the arrival of Huang Chao's army. They spent the Dragon Boat Festival at home. When the rebels crossed the border, they saw people who planted wormwood at home. Not only was no one disturbed, but the military doctor also asked about people's suffering. The rumor that Huang Chao army killed people before was shattered.
4, the role of wormwood
Around the Dragon Boat Festival, it is the best time for Artemisia argyi to grow. In summer, all kinds of mosquitoes emerge one after another. The stems and leaves of wormwood volatilize aromatic oil, producing strange fragrance, which can repel mosquitoes, flies and insects and purify the air. On the Dragon Boat Festival, people can put wormwood and calamus at home or hang them in front of the door, or wear them on their bodies to drive away pests. Wormwood can also be used as medicine, and it can be collected after hanging wormwood on the Dragon Boat Festival.
