Duxiu Peak abruptly rises, steep and precipitous, in Jingjiang King's Residence and has long been called "a Pillar holding Up the Southern Sky". Lying at the southeast foot of the peak, DuShu Cave (Study Cave where Yan Yanzhi, a man of letters of South and Song dynasties once did his reading) is the oldest famous relic in Guilin of a well-known figure. Yan wrote, "Amid Guilin arises the solitary beauty peak, so towering that no peak can match". From then on the hill has been known as the Solitary Beauty Peak.
