In the third year of Zhenyuan, the circuits of eastern and western Zhejiang were divided into the three Zhe circuits: Western Zhe was administered from Runzhou (now Zhenjiang Route), Eastern Zhe was administered from Yuezhou, and Xuan-She-Chi was administered from Xuanzhou. Surveillance commissioners were appointed to oversee each of them (Old Book of Tang).
