Exploring Project 816: A national secret hidden deep in the mountains 🔍 Uncover the history and enter the mysterious underground nuclear world Did you know that in the deep mountains of Fuling, Chongqing, there is a place hidden that was once kept secret by 60,000 people - Project 816.

There are as many as 18 caverns, and more than 130 roads, guide tunnels, branch tunnels, tunnels and shafts. The scale of the project is breathtaking. 🛡️ Indestructible underground Great Wall that can withstand nuclear explosions Project 816 is not only large-scale, but also well-designed.
