The Old Qiang tribes used to be prevailing in the west of China. They separate now into some ethnic minorities. The purpose of this study is to clear their principles of spatial composition of dwellings. In this paper I am concerned with Qiang, one of the Old Qiang tribes. In conclusion, (1) As going up, the spatial hierarchy grows high. (2) The "square" plan of the traditional house is one of the spatial principles. (3) The corners have significance in the room. And the main room is divided into some spatial sections by two diagonal axes.
