Gaodong Cave Tunnel Introduction
E-092 Air Defense Artillery Battalion, Second Company of 20mm Guns. Next to the entrance, you can still see where the tanks used to be parked. The mysterious tunnel entrance is now overgrown with weeds, but it has been specially tidied up for this event! It’s easier to find now~~ The grand tunnel makes us feel so small. It's cool here and perfect for taking silhouette photos, so feel free to pose for various shots!
