Yau Wing Fung's Mountains and Red Trees involves different visualizations of yuan (远). It includes high distance, which refers to looking at the mountaintop from the foot of the mountain, and deep distance, meaning viewing one side of a mountain from the other side. Yau's works reframe the idea of guan (观) and yuan (远) through a contemporary lens. "Guan represents my inner sensibility and feeling when I encounter an object; yuan encapsulates my spiritual pursuit when I paint," Yau once wrote. His works offer new expressions of guan and yuan by reconfiguring perspective, pictorial depth, the balance between emptiness and solidness, and surface texture.
