Introduction to Paoma Liang: Horse hoof nest and point army field were the places where Han Xin practiced troops and horses when Emperor Guangwu of the Eastern Han Dynasty was stationed in Liujiaya. Legend has it that Liu Xiu, Emperor Guangwu of the Eastern Han Dynasty, rode to the top of Taibai Mountain and saw the gentle ridge. His horse galloped, leaving countless "hoof pits" where the horses' hooves stepped. From then on, the planar surface between East and West Taibai was called Paoma Liang.
