In order to prevent the harassment and persecution of ghosts, people put willows and put them on. Willow has the function of ward off evil spirits in people's minds. Influenced by Buddhism, people think that willows can exorcise ghosts and call them "ghost trees". Guanyin dipped willow branches in water to help all beings. Jia Sixie of the Northern Wei Dynasty said in the Book of Qi Yao Min: "Take a willow branch and put it on the house, and a hundred ghosts will not enter the house." Tomb-Sweeping Day is a ghost festival. When wicker sprouted, people naturally inserted willows to ward off evil spirits.
