On both sides of the altar are a set of ritual weapons and objects used for processions. On the wall opposite to the altar, just beneath the lower edge of the roof, is hung a hoanh phi (rectangular wooden plank) inscribed with two Chinese characters 'Nghia khi" (Righteousness and Will). Above the altar is a red baldachin bearing four yellow Chinese characters "Quan Thanh De Quan".
