"Horse stepping on a flying swallow" is a national treasure and a symbol of Chinese tourism. The original is a bronze ware from the Eastern Han Dynasty unearthed in the Leitai Han Tomb in Wuwei, Gansu, China in 1969. It is now collected in the Gansu Provincial Museum. It is one of the most important cultural relics in China and is known as China's "national treasure". It shows the image of a high-head, four-hoofed, high-speed galloping horse with its right back hoof on the back of a flying bird (usually considered a swallow or dragon bird). This work represents the highest achievement of Chinese sculpture art and copper casting process during the Eastern Han Dynasty. Its balanced center of gravity and smooth lines show a high artistic level.
