Religious symbols of ritual purity, such as pomegranate and willow branches, are popular at this time. Some people carry willow branches with them on Qingming or stick willow branches on their gates and/or front doors. There are similarities to palm leaves used on Palm Sundays in Christianity; both are religious rituals. Furthermore, the belief is that the willow branches will help ward off the unappeased, troubled and troubling spirits, and/or evil spirits that may be wandering in the earthly realms on Qingming.
