Introduction to Fenyuan: Fenyuan is the source of Fenhe River. It is located at the foot of Xilouzi Mountain in Dongzhai Town, 30 kilometers southwest of Ningwu County. The source spring gushes out from the stone gutter at the foot of the mountain. There is a 25-square-meter square pond at the exit. The water is crystal clear and almost as deep as the bottom. The water in the pool gushes out from a dragon's mouth carved out of a stone through an underground passage and flows into a wide river. There is a stone carving of "Fenyuan Lingzhao" horizontally above the dragon's mouth. This is the source of Fenhe River and is known as the "root of Jin".
