This work was completed in 1987, and is a part of Yuyu Yang's stainless steel "Cosmos Series."The phrase "heaven and earth" is the way that Chines e describe all of nature, and it is a way to describe the beauty of "symmetry"and "completeness." It also has a feeling of being vast and unlimited. The Chinese concept of Yin and Yang is concisely contained in this phrase, including form and the formless, real objects and formless spirit, the self and perfect oneness. Yuyu Yang has always liked to find creative inspiration in the contemplation of this concept. Between heaven and earth exist all the vast mysteries of the cosmos, stretching without limits, stimulating eternal glory, attracting and dissipating karma, filling the cosmos with dazzling beauty. It is "destiny" to complete the propagation of life, the flourishing hopes of countless "contented lives."
