World Mysteries - Pyramids of China...?

World Mysteries - Mystic Places - Pyramids of China: "The worlds largest pyramid is rumored to be in Qin Lin county in a 'forbidden zone' of China, estimated at nearly 1,000 ft high and made of impounded earth and clay, and holding vast tombs. The Chinese govt have long denied the existence of 100 or so pyramids though the increasing tourism to the Xian tombs area (the Terracotta Army) is threatening the secrecy with tourists climbing the 25-100m pyramids for themselves."
