Since beam and eave are not stretched out to protect windows from rain and they only can cover the walls below, thus a rain shield is set on the roof to protect the door and windows, but also seen as a kind of decoration on buildings, combining both practicability and aesthetics.
Above the lintel of the door, there are two to four layers of sandalwoods in crisscross, making them into sally-like coaks. The amount of rafter and the length of sandalwood increase by layer, and mud and macadam are paved on the top layer of sandalwood, which presented lower in the front and higher in the end, becoming a narrow-stripe slope. At the end, stone flags and tiles are used to accomplish the roof, with colored paintings.
Toilets are suspending outside the back walls, with an independent door. The positions of toilets are disposed staggerly, so that excrement can drop into the cesspool on the ground directly, besides household wastes and sewage are congregated here as well. In this case, this kind of toilet is still kept indoor, but isolated with living rooms, which is extremely suitable for this sort of dry and cold climate of the plateau, making it convenient in covering and cleaning. No bad smell and keeping clean are two advantages it possesses of.
