Introduction to Zhuangyuan Well: This well was dug in the Song Dynasty. The well is 12 meters deep, with a wellhead diameter of 0.24 meters, a bottom diameter of 2.2 meters, and a water depth of 4 meters. The water in the well is as clear as a spring, with a sweet and salty taste. It is said that it is connected with the spring eye of Qinhuangtai Octagonal Dragon Well and the eye of the sea, so it is called "holy water". The water from this well is related to literary fortunes in the academic field. Literati wash their faces with the "holy water" in the well, and their literary thoughts can flow like a spring. Using the well water to polish ink can make flowers bloom in their pens. Later generations call it "Zhuangyuan Well".
