Zhao Ling-The Secret of the Emperors Tomb

Emperor Taizong is revered today as a wise ruler who led China into a golden age. His reign saw the invention of paper, book printing, gunpowder, and the compass, hundreds of years earlier than in Europe. After his death in 649, he was buried in a sumptuous mausoleum in the mountain Zhao Ling. Chinese archaeologists are searching for its entrance, aided by European technology.
