Beyond the Great Wall

Nat Geo WILD goes inside the sprawling Tibetan plateau that makes up one-quarter of China's expansive landscape.

Go inside Tibet's unique culture, defined by more than a thousand years of Buddhism. And learn more about why the emperors of China built the Great Wall to keep out the nomadic tribes from Northern China.
