Do you know the origin of inserting wormwood in Dragon Boat Festival?

It is said that in ancient times, a boa constrictor turned into a monk in order to practice, and spread rumors in the city that if he wanted to go to heaven, he had to go to a cave on the mountain. After crossing the cave, he can go to heaven. Many people believed it and went to the cave one after another, but I didn't expect that this was actually a scam. The cave is a place where boa constrictors eat people, and everyone who goes there is eaten by boa constrictors.

On May 5th, it happened to be Duanyang Festival, and the python was dismantled. People in the street were ecstatic and praised Zhao Fuyuan's achievements in unison. People rushed to Yuelu Mountain to see the python cave. This python is so big that it scares people to death. Countless people ate it later. From then on, every household hangs calamus leaves and drinks realgar wine during the Dragon Boat Festival.

This tradition has been handed down.
