Four rooms in the hall take the southwest gate, and several rooms in the south and west of the hall are good.

Put the second room on the east side of four houses, and some of them are divided into five rooms, one and a half rooms in the east, one and a half rooms in the middle, one and a half rooms in the west, or one and a half rooms in the west. Houses in rural areas are built symmetrically on both sides, with rooms in the middle, which are generally larger on both sides, so if four rooms are large on one side, then the two rooms in the middle are sitting in the hall, one on both sides.
