How did Xichang Qionghai come into being?
It is said that Qionghai used to be a county town, and later Qionghai was formed due to the subsidence of crustal movement. Others say that the ancient basin of Anning River is a dammed lake formed by earthquake. In short, there are many sayings, the most popular one is that the earthquake caused the county seat to sink.
However, a number of Neolithic sites and unearthed pottery and net pendants around Qionghai in the 1980s show that they were formed in prehistoric Qionghai at the latest, and Xichang City sites and unearthed cultural relics also show that the theory of "subsidence lake" cannot be established.
