滇池
Dian was an ancient kingdom situated in modern Yunnan, southwestern China. According to Han historian, Sima Qian, it was established in 279 BC by Zhuang Qiao, a general of Chu during the Warring States period. He was sent to the region around Dian Lake as part of a Chu military campaign. When the Chu homeland was invaded by the Qin, Zhuang Qiao decided to stay in Yunnan and established the Dian kingdom. The Qin dynasty was subsequently overthrown by the Han, and the commanderies of the new dynasty, Ba and Shu, bordered Dian.
