With Tianma Mountain to its east, Jishan Mountain is 38.9 meters?above sea level and covers about 7 hectares?of land. It is named after Lu Ji, a famous writer in the Western Jin Dynasty (AD 265~316).

At the foot of the mountain, there is a village called Pingyuan village, also named after Lu Ji, as it was appointed Pingyuan Neishi. As the mountain is small, it is also called Xiaoji Mountain. Due to long-term quarrying, one third of the mountain has gone.
