Làngqióng
Langqiong lies north of Erhai, among the mountains and waters that feed the lake. The Yuan established the county in 1274, and under the Ming it belonged to Dengchuan Prefecture. A Ming geographical account describes the river flowing south past the foot of the Cang Mountains into Erhai, as well as warm springs in the district. One spring at the foot of Sanying Mountain was visited for bathing throughout the year.
