Bags are hung from the central roofbeam of the main hall. The bag on the left holds the five metals, while the bag on the right holds the five grains. This represents men working in the world and women working in the home, hence halls full of gold and jade, and a bountiful grain harvest.
掛在棟樑上的「棟樑袋」，左邊掛五金，右邊掛五穀，象徵男主外、女主內，金玉滿堂、五穀豐收。
