Yishui: the ancient name of water, that is, Qingjiang River, a tributary of the Yangtze River in western Hubei, and its upstream rivers.
Yidu: the name of ancient county, located in the middle of the Three Kingdoms Shu, in the northwest of Yidu City, Hubei Province.
Li Daoyuan of the Northern Wei Dynasty said: "Yishui connects Yidu in the north and enters the great river in the east, which is the ratio of Jing and Wei. Also known as Washan Beixi, the water passes through the Rocky Mountains and has no shore. Its water is empty, overlooking the fish, such as taking the air. "
Yishui flows into the river through Yidu in the north and east, and the two waters are clear and turbid. Yishui, also known as Washan Beiliu, is surrounded by Rocky Mountains, and there are basically no earth dikes. The stream is clear, as if there is nothing in the air. Looking down at the fish is like floating in the air.
