YICHING is a time-honored classic in the history of Chinese civilization with a profound connotation. It is not only called as the "top of all classics", but also the source of Chinese philosophy. YICHING integrates the heaven, the earth and the man’s world, and elucidates the life philosophy of self-cultivation and family management. The production extracts the name of YI in order to express the choreographer's understanding of "YI", in addition, it also draws on the basis of creativity on the hexagrams, which gives birth to specific movements and images. Taiji elements are also adopted to develop movements, expressing the dynamic balance of "YI" through formal YIN and YANG transformation simultaneously fusing the rigidity and softness, and also try to express the thought of Unity of Heaven and Man, and the artistic conception that the greatest truth is the simplest.
