Many people are curious whether wormwood has been hanging on the door all the time, but in the past, wormwood could be hung on the door for a long time. Wormwood itself is a perennial herb or shrub with a strong smell. Hanging it on the door can improve our feng shui fortune and help us resolve evil spirits that may enter our home. We usually hang wormwood on the door during the Dragon Boat Festival, when we go home from sweeping graves, when we are released from prison and when we experience great disasters. No matter how long we hang it, there is no problem, but it should be noted that wormwood will be damaged by air drying.
