Yandang Mountains are situated in Yueqing city, east China's Zhejiang province. There are a group of brave men who "fly" over the cliffs. They are the famous "spiders" in Yandang Mountains.
Â
In ancient time, the "spiders" climbed across the Yandang Mountains to pick a precious herb - dendrobium- as traditional medicine materials. As time passes, the precious wild herbs disappeared gradually. The successors developed the rock climbing skill to a trilling performance in Yandang Mountains.Â

Zhou learned to "fly" over the cliffs since he was very young. His family had made a living picking dendrobiums for generations.Â
