Introduction to Hechao Spring: There are two spring pools standing side by side on the top of Qidu Peak of Fucha Mountain. The water in the North Pool is deep and clear, named "Hequan"; the water in the South Pool is shallow and turbid, named "Chaoquan". The water level of the Second Spring is stable all year round. It never falls when it is taken, and it does not rise unless it is taken. No matter whether it is heavy rain or drought for several months, the water level in the pool will only differ by a few centimeters. Ouyang Xiu, a great writer in the Song Dynasty, praised it as "the seventh spring in the world".
