Introduction to Jiang Wei Well: In front of the Niutoushan ancient temple ruins, there is an oval-shaped ancient well with a diameter of about 3 meters and a depth of 2 meters, named "Jiang Wei Well". During the Three Kingdoms period, Shu and Wei were at war. Jiang Wei, the general of the Shu Han Dynasty, was trapped in Niutoushan. There was a shortage of water in the camp. Zhuge Liang asked Jiang Wei in a dream. Jiang Wei worshiped the sky and worshiped water, and he got half a well of water, which relieved the crisis of drinking water. This well never dries up for long periods of drought or overflows for long periods of rain. The color of the water changes with the clarity and turbidity of the Jialing River, making it a wonder in the world.
