In 1945, a U.S. pilot accidentally saw a huge pyramid, and later an entire valley with pyramids in China, although previously it was certainly not known about it.
Twenty years after that, the media mentioned the Chinese pyramids, but then at one point everyone forgot about them. And in the 2000's, the Chinese government itself acknowledged the pyramids existed.
But almost immediately a military base was established there and the area became inaccessible for any research. Coincidence?
To this day it is not known what kind of pyramids in China, what was found in them, and how old they are? However it is possible to assume that China is not going to reveal these mysteries.
