Traditional Chinese painting was fundamentally an abstract art form. Objects in a painting were not a direct copy of the nature world following the principle of perspective. It was rather a combination or harmony between the nature world and human emotion, a product of"heaven(nature)and human". The description of objects in Chinese painters’ paintings was no means accurate and few concerned about such factors as colors, principle of perspective, anatomy, surface feel, and relative size. What they would like to achieve was a world in their mind of non materials. The nature world was not an object for them to make a true copy and it was rather elements for them to build their own world.
