Introduction to Longquan Well: Longquan Well was built in the Ding Chou Year of Jiaqing in the Qing Dynasty (AD 1817) and is located in the back street of Lanxi, Datong Town. Since this well is located at the foot of Changlong Mountain, there was a spring here before the well was built. The spring water flows all year round. In order to facilitate the storage and use of the spring water, She Yiyu dug and built a well at the spring. The well was three feet deep. More than enough. Because people call the spring Longquan, the owner named the well Longquan Well.
