The name of Mount Emei dates back to the Western Zhou Dynasty. According to the Jin Dynasty song "Records of Huayang Kingdom", "Du Yu takes Baoxie (now Hanzhong, Shaanxi Province) as the front door, Xiong 'er (now Qingshen County, Sichuan Province) and Lingguan (now northwest of Lushan County, Ya 'an, Sichuan Province) as the back door, and (now Dujiangyan City, Sichuan Province) and Emei City, Sichuan Province as the city walls."
Jin Zuosi wrote in Shu Du Fu: "Draw two rivers and streams to resist the heavy resistance of Emei." But why is it called Emei?

Hydrological situation
The hydrogeological position of Emei Mountain belongs to the Da (Dujiang) Qing (Yijiang) water system, and there are five natural rivers in the territory: Emei River, Linjiang River, Longchi River, Shihe River and Huaxi River.
The regional variation of surface runoff in Emei Mountain is similar to precipitation. Its runoff depth is as high as 1800 mm, which is three times that of the west bank of Dadu River.
The groundwater in Emei Mountain mainly occurs in structural cracks and limestone dissolution. However, because the Emei Mountain fault passes through it, the fracture width of the fault reaches 50 ~ 100 meters, and there are many secondary fault structures, which leads to the destruction of most of the main aquifers.
Shihe Shihe River originates from Mount Emei Wanfoding and Jieyin Temple, flows through Tongchangba and Xiaocuntou, and reaches Jiaopingba (Jiaopenba). A spring water overflowed from Longdong Village, flowed into the south of Hongya County, flowed into Wuhe and Huaxi, and flowed into Qingyi River in Hongya Zhige Township.
Zhanggou River is one of the main tributaries of Linjiang. The Dragon Camel Trough, which originated in Emei Mountain, flows through the Wild Boar Dam, Pianqiaogou and Zhanggou Power Station to the southeast Yaoyaoshi. The Dagou River, which originated in the sand dam, and the Huangyubagou, which originated on the land, join the Erdao River under Guanyin Bridge.
