Qiang architecture has a unique style and superb craftsmanship. The materials used are mainly stone, which is very different from the Han architecture, which is mainly wood, rarely uses stone, and pursues the basic principle of "virtue in wood". Qiang architecture combines the three main forms of traditional Chinese architecture: the tent style of nomadic peoples, the cave style of Han people, and the main features of stilt-style architecture, with a simple style. The Qiang architecture inherits the tent style of nomadic peoples, which is reflected in the fact that the central column structure is still completely preserved in its interior, and the Qiang people have evolved the central column into a spiritual column in the interior space. This form of expression is closely related to the historical experience of the Qiang people. A large part of the Qiang ancestors migrated from the northwest to the upper reaches of the Minjiang River. Although the mode of production changed from nomadism to farming, many cultural characteristics of nomadic peoples were still preserved, becoming a distinctive feature of Qiang culture. The Qiang culture has a diverse structure and is particularly deeply influenced by Han culture. After settling in the upper reaches of the Minjiang River, the Qiang people made adaptive changes to their architectural forms while retaining some of the cultural characteristics of nomadic peoples. For example, the tent-style dome structure was restricted by geographical conditions, and more importantly, because the dome structure had become a symbol of power, order, and hierarchy of the ruling class in the mainstream culture of the Han people in the Central Plains, so the Qiang people pragmatically chose the cave-style flat-roof structure. The group architecture of the Qiang people is an integrated layout, and the layout of the single building is in the form of a courtyard with a closed exterior and an open interior. It is reasonable and orderly, not only influenced by the wooden structure of the Siheyuan in the Han area of the Sichuan Basin, but also has traces of imitating the northern Siheyuan form. Moreover, the "Siheyuan" of the Qiang people has further developed into the air on the basis of the Siheyuan form of the Han people, forming a setback Siheyuan style with Qiang characteristics.
