Brief Introduction of Shenyang Wei Zi Tunnel

The first three archaeologists who entered the mausoleum were blocked by several boulders after entering the tunnel 100 meters. At the end of their rope, they had to go home, but at this time they met a big trouble. In the narrow tunnel, three people couldn't turn around at all. They quickly spread the news to the ground command center, and later, with everyone's help, the three men survived.
