Introduction to Liulonggou: Liulonggou is a ravine in the northeast of Zhaiding. The mountains are steep and the valleys are flat, leaving traces of terraces. According to legend, the Dragon King Prince descended to earth here because he fell in love with Wang Fang, a girl from Culai Mountain Village. He changed his name to Liu Long. The men farmed and the women weaved and settled here. In memory of Prince Long, the ditch was named Liulong Valley.
