Ancestral hall is a place where the soul tablets of the same clan are worshipped.Generally speaking, only clans that had made achievements are allowed to build the ancestral hall.Therefore, the construction of the ancestral hall symbolizes the prestigious social and economic power of the clan.In terms of construction, clan members are particularly about the place of construction (usually built in the middle of the village), construction materials and decorations.This could be observed from the existing ancestral halls in Hong Kong.
