During the Song Dynasty, there was a Pingjiang Military Prefecture, which later was raised to the status of a regular Prefecture. It corresponds to the present city of Suzhou, Jiangsu. The original was a city map carved on a stele. At the bottom, the Public Pharmacy (see Fig.235 ) and the Imperial Academy of Medicine (Yi yuan) are labeled. (Original stele preserved at the Suzhou Museum of Stele Inscriptions, Jiangsu Province.)
