Name evolution

Erhai Lake was called Ye Yushui, Ye Yuhe, Ye Yuze, Xi 'er River, Er River and Kunmichuan in ancient times. Erhai Lake was finally named after Er, either because it looks like a human ear or because it embraces Er like the moon. The name "sea" comes from the customs of Yunnan. One of the eighteen eccentrics in Yunnan is called "the lake is called the sea". In other words, lakes are often called "sea" in Yunnan.

With the development and change of society, the name "Ye Yushui" is often used in ancient literature. "Xi 'er River" mainly refers to a section of the river where the southwest exit of Erhai Lake flows westward and finally merges into Yangbi River. With the disappearance of Kunmi tribe, Kunmi Biography is rarely used. Erhai Lake has become the most popular name of this lake.
