Gallery road

They were most notably used in the Qin Mountains linking the Wei River and the Han River valleys. The first gallery roads were built during the Warring States period (476-221 BC) and used by Qin to invade Shu and Ba. They were fully consolidated into a thriving network during the Han Dynasty.
