An easy way to orientate yourself to the topography of China.
If your palm is China’s heartland; then the largest ethnic minorities are around your digits: the Tibettans on the mountains of your third and fourth fingers; the Uyghurs on the deserts of your first and second; the Mongols on the steppes between your finger and thumb; and the Manchus on the plains of your thumb. Your wrist and the bottom of your hand are the sea coast.
The Great Wall runs along the top of your palm, originally to keep the Mongols and Manchus out. The Yellow River waters the north of your palm; the Long River waters the middle and south; and the Pearl River runs down to the South China Sea.
The ancient capital of Xi’an is in the middle of your palm. Today’s capital, Beijing, is on the ball of your thumb; the financial capital, Shanghai, is in the middle of your wrist; and the international hub of Hong Kong, is on the bottom of your hand.
