The original meaning of this phrase is that a
piece of white silk must be prepared before one can paint. The concept was then
extended to mean that beauty comes from natural simplicity. From this,
Confucius (551-479 BC) put forward the notion that benevolence and righteousness are fundamental and the code of ethics
secondary, emphasizing that the teaching of the rites originates in human
nature. This concept was later introduced into literary and artistic creation
and criticism, which advocates that elaboration should be based on substance,
and that style and substance should be compatible and complement each other to
bring out the natural beauty.
