In the millennium ancient capital Chang'an, the one-hundred-meter corridor extending within and without the city wall and the thirteen sets of ice screens brought the crowded visitors into contact with the long history of the city, capital of 13 dynasties in ancient China. As they moved closer to or farther from each other in music, the crescent-shaped platform and the main stage created a multi-level performance space. Multi-media images were interspersed with shiny water surfaces and the central stage in an irregular shape rotated and elevated in 360 degrees, quite flexible and changeable. Here, Jiahe fully displayed her innovation, ingenuity, variety and wisdom, enabling technology to be combined with culture and stages and performers to move together,thus creating a fusion of feelings with the natural settings. Novelty and changes are just the infinite charm of mechanical art!
