She died in 163 BC. When they found her in 1971, her hair was intact, her skin was soft to the touch, and her veins still housed type-A blood.
Now more than 2,000 years old, Xin Zhui, also known as Lady Dai, is a mummified woman of China’s Han dynasty (206 BC-220 AD) who still has her own hair, is soft to the touch, and has ligaments that still bend, much like a living person. She is widely recognized as the best-preserved human mummy in history.
Xin Zhui was discovered in 1971, when workers digging near an air raid shelter near Changsha practically stumbled across her massive tomb. Her funnel-like crypt contained more than 1,000 precious artifacts, including makeup, toiletries, hundreds of pieces of lacquerware, and 162 carved wooden figures which represented her staff of servants. A meal was even laid out to be enjoyed by Xin Zhui in the afterlife.
But while the intricate structure was impressive, maintaining its integrity after nearly 2,000 years from the time it was built, Xin Zhui’s physical condition was what really astonished researchers.
