Guangzhou (廣州) was the southern province centred on what is now Guangdong and neighbouring coastal regions. Under Eastern Wu it lay at the edge of imperial authority and was difficult to reach, which made it a convenient place of exile.
In 245 Gu Tan, Gu Cheng, and Zhang Xiu were banished to Jiao/Guangzhou after being accused by Quan Cong’s faction of inflating their merit. Other disgraced figures, such as Lou Xuan, Zhang Bu, and Puyang Xing, were also sent to the far south. Life there was harsh compared with the Yangtze heartland, and several of these exiles died away from court.
