When do you put wormwood at the door for the festival?

Put wormwood at the door during the Dragon Boat Festival.

Dragon Boat Festival is a poisonous day and an evil day in the eyes of the ancients. This idea has been handed down in folk beliefs, so there are various customs of seeking peace and solving disasters.

This is because the summer weather is hot and dry, people are easy to get sick and the plague is easy to spread; In addition, snakes and insects bite easily, so be very careful, which forms this habit.

Reasons for the custom of hanging wormwood on Dragon Boat Festival;

Both Artemisia argyi and Acorus calamus contain aromatic oil, so they can be used as pesticides to kill pests and diseases. During the Dragon Boat Festival, the summer solstice approaches, the weather turns hot, the air is humid, mosquitoes breed and epidemics increase. Ancient people lacked scientific concepts and mistakenly thought that all diseases were caused by ghosts and evil spirits. Therefore, Artemisia argyi and Acorus calamus were tied into human shapes and hung in front of the door in the early days of the festival to drive away ghosts and evil and keep healthy.

In fact, it is the fragrance of these two kinds of grass that really purifies the environment and repels the plague. In southern China, people are used to drinking calamus wine during the Dragon Boat Festival, so its medicinal effect is more direct. Usually, Acorus calamus is chopped before the festival, mixed with realgar, soaked in wine, and can be drunk on holidays.

There are reasons for hanging wormwood, calamus (Pujian), pomegranate and garlic at the entrance of Dragon Boat Festival. Usually mugwort leaves, banyan trees and calamus are tied into a bundle with red paper and then inserted or hung on the door. Because Acorus calamus is the first of the five auspicious symbols in the sky, it symbolizes the ominous sword, because the growing season and shape are regarded as "the breath of a hundred yin", and the leaves are sword-shaped and can be inserted at the door to ward off evil spirits.
