What things did Guo Degang’s cross talk and other literary and artistic works predict?

In the cross talk "I Want to Travel", Mr. Guo talked about traveling to Egypt. He heard that there was a mummy there. He thought of the Chinese Terracotta Warriors and knew that there were a number of mummies. Teacher Guo joked that counting is required at night, which is too high-tech. At night time, a bunch of mummies were laid down, and a caretaker came, 64, here! 65, here! 67, oh, no one agreed to 67, so he told Qian to wrap you in a white cloth and leave it there. Yu Qian said seriously: "My dad and I were standing by the Terracotta Warriors and Horses." People pretending to be mummies and Terracotta Warriors and Horses, something that appeared in jokes, unexpectedly came true again. According to an old news, on September 16, 2006, a German young man made a homemade Qin Terracotta Warrior costume, painted his face with earth color, dressed as a Qin Terracotta Warrior and jumped into the restoration area of ??Pit No. 1.
