Introduction to the Big Water Well: The Big Water Well is actually not big, just a small well one meter square. The water from the big well comes from a spring on the mountain. It is crystal clear and never dries up all year round. It is the source of water for hundreds of people in the Li family. The patriarch Li Gaiwu personally wrote the three characters "Dashuijing" outside the wall. Each character is 70 centimeters square. The running script is incised and vigorous.
