There is a ten-meter long small tunnel at
Sun-Long Trail. It used to be the main railroad for transporting coal mined
form Huyi-Erkeng. The glory of Yingge’s mining history has been created by
hundreds of miners. However, the mine closed down years ago due to changes in
energy demands. The railroad became a hiking trail, and Erkeng Tunnel is now a
scenic spot for hikers to rest.
