Yumu Mountain is situated in the Hengyang Basin of the central Hunan hilly area, within Yumushan Township, Zhengxiang District, Hengyang City, Hunan Province. Its core scenic area covers about 4 square kilometers, and the combined regional area is approximately 20 square kilometers.

    Lying to the west of downtown Hengyang, the main peak stands at an altitude of 238 meters with a relative height of 180 meters. Yumu Mountain was originally named Yunfu Mountain.

   Cangjie Pian, written by Li Si in the Qin Dynasty to standardize Chinese characters, records:

     "Yunfu Mountain is broad and gently rolling."

    Since ancient times, the mountain has been named Yumu (Rain Mother) Mountain for its renowned efficacy in rain-praying rituals.

     According to Records of Jingzhou compiled by Sheng Hongzhi of the Eastern Jin Dynasty:

    "In eastern Xiang lies Yumu Mountain, upon which there stands a shrine altar. Prayers for rainfall have always been answered with timely blessings of rain, hence the mountain’s name."
