One to three days before the Sacrificial Deliverance Ceremony, bamboo posts are set up at sites such as railway stations, Ching-An Temple, Main Altar and Cultural Center. Large leafed green bamboo is often used as posts for hanging the lamps, signifying a job being complete from beginning to "a good end." Lamps and banners are hung on the posts. Raising bamboo posts serves two purposes; one is to invite all heavenly deities to supervise the proceedings of this ceremony and to enjoy merits, the other is to allure the wandering ghosts to come to share the sacri- fices offered to them. Lamps and banners that are visibly hung along main roads, railway stations and bus terminals are for promoting the event and adding to the festive atmosphere.
