The work entitled "Subconsciousness" was painted in 2007, simply in beige and dim gray. With the least colors, the painting appears to be extremely limpid. The composition and colors indistinctly present the beauty of a void. The forceful contrast of light and shade as well as the mesh of lines and blocks creates an indistinct atmosphere. The artist elaborates the limpidity of ink wash painting, makes use of the properties of oil paint that drips, and portrays the intangible "sub-consciousness" in a symbolic way instead of with substantial contours. Based on the understanding of space, Yang's poetic scenery leads viewers' sights moved with the colors and their memories revealed. The bemazed sub-consciousness wafts in an abstract space freely and it creates a kind of visual effect that being empty in beat and abstract in concreteness can be felt. It is rational but romantic, delicate but wild.
