Introduction to the Educated Youth Bridge: The Educated Youth Bridge was built in the early 1970s by Hangzhou educated youth composed of cadres and their children from Zhejiang provincial government agencies who joined the team in Yunlang Village. Because this bridge is connected to Yunlang Village in the east, it is also called "Yunlang Bridge". The bridge is a concrete double arch structure with a total length of 150 meters. There are three huge "Educated Youth Bridges" carved by local villagers in memory of the educated youth on the bridge.
