Dian Lake
Dian was an ancient kingdom situated in modern Yunnan, southwestern China. According to Han historian, Sima Qian, it was established in 279 BCE when King Qingxiang of Chu sent a military force to the southwest. Zhuang Qiao, a general of Chu, reached the Dian Lake as part of the Chu military campaign. When the Chu homeland was invaded by the Qin, Zhuang Qiao decided to stay in Yunnan and adopt the native ways, establishing the Dian kingdom. The Qin dynasty was subsequently overthrown by the Han, and the commanderies of the new dynasty, Ba and Shu, bordered Dian.
