Buzi (fortification)
Buzi are small forts built along the northern frontier of China. They are prevalent in the Loess Plateau of Shaanxi, Gansu and Ningxia provinces, usually square or oval (as hill forts) and built out of rammed earth walls. Geography The forts are built on hilltops, at strategic locations or within villages. They were mainly financed by local notables, and constructed by villagers of the area. A large number of forts are found in Tianshui (over 500) and Dingxi prefectures, totalling over 1400 forts. One of the densest concentration of forts is Tongwei County, which has the nickname "thousand forts county" (). Qin'an County is home over 200 forts including three larger castles.

The Loess Plateau is a plateau in north-central China formed of loess, a clastic rock, clastic silt-like sediment formed by the accumulation of Dust#Atmospheric, wind-blown dust. It is located southeast of the Gobi Desert and is surrounded by the Yellow River. It includes parts of the Chinese provinces of Qinghai, Gansu, Shaanxi and Shanxi. The depositional setting of the Chinese Loess Plateau was shaped by the tectonic movement in the Neogene period, after which strong southeast winds caused by the East Asian Monsoon transported sediment to the plateau during the Quaternary period. The three main morphological types in the Loess Plateau are loess platforms, ridges and hills, formed by the deposition and erosion of loess. Most of the loess comes from the Gobi Desert and other nearby deserts. The sediments were transported to the Loess Plateau during interglacial periods by southeasterly prevailing winds and winter monsoon winds. After the deposition of sediments on the plateau, t ...
