Folk proverb says: "Plant willows during the Qingming Festival and moxa on the Dragon Boat Festival." During the Dragon Boat Festival, people regard planting mugwort and calamus as one of the important parts of celebrating the Dragon Boat Festival.

During the Dragon Boat Festival, every family sweeps the courtyard, inserts calamus and moxa sticks in the eyebrows of the door, and hangs them in the hall. It is understood that as early as the Jin Dynasty, people had begun to hang mugwort (ie mugwort) on their doors. In the Northern and Southern Dynasties, mugwort developed into mugwort people.

Notes on hanging wormwood:

First of all, when hanging wormwood, hang even numbers, remember not odd numbers. Usually it is hung on both sides of the door so that the aroma of mugwort can be brought out to the best extent. In addition, when hanging mugwort, you should also pay attention to whether there are pregnant women or babies at home. This is because their respiratory tracts are relatively delicate. Harvest mugwort when the sun has not yet risen. The aroma will be richer and more valuable.
