Dai Jia's upstairs living room has three pillars, two of which are separated from the living room side by side and one is next to the fireplace. There are two in the bedroom, and the outside one is called "auspicious column" for rest; The one behind is used after death, and it is called "Ascending Pillar". If a family member dies, the family will lean on this pillar to bathe, dress and wrap their bodies, waiting for cremation. One by the fireplace is absolutely not allowed to rely on, and it is the "pillar" of Dai's family. If you lean against the post, it means disrespect to the host.
I am plagiarizing, I hope to adopt it!
