This paper studies the main hall of Huashizhu Temple in Guzhai village, Gaoping county, Shanxi province, which was built in the Taihe reign period of Jin. The discussion is based on data collected via survey and mapping by the School of Archaeology and Museology of Peking University in 2019. Through comparative analysis with other Song and Jin buildings in southeastern Shanxi, the characteristics of the system of scale used for local (and regional) Jin temple architecture were discovered, analyzed, and interpreted.
