On January 18th, in the Bussuri Military Tourism Scenic Area in the Oroqen Autonomous Banner, Hulunbuir City, Inner Mongolia Autonomous Region, the entrance of the "cavern" was designed as a "U"-shaped door. This design is highly concealed and has the function of three defenses.
From the 1950s to the 1970s, in the northernmost part of China, it lasted more than 30 years and cost 2.7 billion yuan to build China's largest military logistic material reserve and supply base.
Now it has become a tourist area.
