The ancients cloud; Painting is divided into four categories; Yipin, Shenpin, Miaopin and Nengpin are all based on one product. The "style" of painting has always been a special requirement of Chinese painting. One product advocates artistic conception, the divine product pays attention to learning and accomplishment, the wonderful product pursues aura, and the functional product pays attention to interest.
It can be called: vivid image, accurate grasp of the image of objective things, this product can be copied and learned.
Wonderful products are called: exquisite pen and ink, skillful skills and handy methods. This product can also be copied and learned.
The artifact product is called it: depicting the spiritual essence of things has reached the highest level, and this product can also be used as a model to copy and learn.
When the technique of pen and ink reached its acme, Yi Pin called it "the method of impossibility". That is, the realm of "painting becomes familiar when it is born" is the result of "fantastic ideas" and "skillful hands", and one can't lead by example.
