	Liu-gong Valley also lies on the periphery of Middle Yandang Mountains. In 1132, the county magistrate of Yue Qing County organized workers to dig a canal and build the dykes and dams, which solved the flood and protect the benefits of citizens. To memorize him, people call the valley Liu-gong Vally. It is said that in Jin Dynasty(265–420), a literary celebrity named Ruan-fang(Chinese: 阮放) has lived in seclusion and Wang Xizhi(Chinese: 王羲之) came here to visited him. Therefore, lots of poets and calligraphers visited here and left their work.
