The source temple was built because of the source of Hongshan Spring, and its temple was built on the source of Hongshan Spring. Hongshan Spring, also known as Gulu Spring, is said to sing here when the spring tide is surging. "Shan Hai Jing" records: "There is no vegetation on the mountain of the fox, and shine on you is better than water." This is the earliest historical record about Hongshan Spring. Hongshan Spring is the largest underground spring in Jinzhong and has always been the lifeline of Jiexiu water conservancy. She has made indelible contributions to the history and economic development of agriculture, ceramics, incense making and water milling in Jiexiu. In particular, the records of porcelain kilns in temple monuments provide precious historical materials for the study of ceramics in the Song Dynasty. Shen Yuan Temple has always been the center of the local regime and people in managing and utilizing water resources. There are more than 20 stone tablets in Shen Yuan Temple, which record the achievements of Wen Yanbo, a famous figure in the Song Dynasty, in creating the Three Rivers. It also includes the record of Wang Yikui's management of Hongshan water conservancy and its disadvantages in the Ming Dynasty, as well as the historical facts of other famous people on water conservancy, water conservancy construction, water conservancy regulation, water law, water pipes, water dispute settlement, project layout, water saving and pollution control. Hongshanyuan Temple, with relatively complete historical and cultural remains, has preserved the development track of Chinese water conservancy culture for more than 1000 years, and has its unique cultural relics and historical value.
