Zituan Mountain

　　Huguan County has a summer resort called Zituan Mountain, situated in Shuzhang Town, 60 kilometers southeast of the county. Also known as Cuiwei Mountain and Baodu Mountain. During the Jin Dynasty, the traveler Baopuzi, after visiting famous mountains and scenic rivers across China, once wrote: “The finest mountains under heaven are the Five Sacred Mountains in the south and Baodu Mountain in the north.” The northern Baodu Mountain refers to this very place. The mountain was renamed Zituan Mountain by imperial decree during the Song Dynasty because of a natural limestone cave formed 300,000 years ago at its mid-slope. The cave faces west, and every sunrise and sunset, bursts of purple mist spew from its mouth—hence the name “Purple Mist Mountain.”
