Woo and Yo come from “Tao Te Ching” by Laozi, the philosopher of ancient China. In Chinese, Woo and Yo are the two basic elements creating the whole universe; they rely on each other so that life goes on. Laozi said: The square, perfected, can not be shaped. Music, perfected, can not be heard. Spectacular, perfected, can not be seen. Tao, perfected, can not be spoken.
