Acupuncture
Acupuncture fundamentally involves the insertion of fine needles into acupuncture points (of which there are at least 2000) that lie just beneath the surface of the skin.

Great Wall
Before the Great Wall of China existed there were many tinier walls or earth works constructed by several different states. In 220 BC, under Qin Shin Huang, those disparate sections were joined together to form a united defense system against invasions from the north.

Mountaineering
With nine of the world's 14 peaks above 8,000 meters in China, including the two highest (Mt. Everest and K2) and countless others above 6,000 meters in height, China has been the focal point of mountaineers around the world for years.

Paleontology
As a child one of my favorite books was 'The Lost World' by Sir Arthur Conan Doyle. Of course, it was probably the abridged version that I read, for I remember several colorful pictures of a bovine looking Brontosaurus, a terrifying Tyrannosaurus Rex, and a most dashing Professor George E. Challenger.
