Xi’an is one of the 10 oldest cities in the world. Around 1.15 million years ago, Lantian man, a subspecies of Homo erectus, lived in the area, marking one of the earliest stages of human civilization. Historically known as Chang’an, the city served as the imperial capital of 13 dynasties, including the Qin, Han and Tang. For several millennia, Xi’an has created a rich sporting heritage, represented by Chen-style tai chi, Xingyi Six-harmony Broadsword and Fuxing lion dance. Its time-honored history has also added charm to modern sporting events. For example, the Xi’an City Wall International Marathon has been held for more than 20 years on the ancient city wall constructed during the Ming dynasty.
