YU-YU YANG's later "Stainless Steel Series" represents the mature period of his creative career, incorporating Chinese ecological aesthetics and Buddhist philosophy into advanced, modern materials and simple abstract forms. His stainless steel mirror works reflect a purity and cleanliness akin to Song porcelain, incorporating the surrounding environment and viewers into the pieces. Through curved viewpoints, they soften the atmosphere, achieving a harmonious unity with the environment and the viewer. Yang Yingfeng's art takes nature as its teacher, respecting, beautifying, and protecting nature while integrating it into everyday life, embodying the contemporary concept of "art in life, life in art."
