Shuangqiao (Double Bridges) Gulley is 34.8 km long with an area of 216.6 sq km. The gulley is flat with brooks flowing crisscross murmuring. The slopes are densely covered by primitive forest. Dozens of mountains including Mt. Wuse, Lieren Peak thrust themselves towards the sky, some like rhinoceros looking at the moon, some like lion roaring, all with different postures and colors, presenting a likeness both in shape and spirit.
