Forgive me. I was thinking of Japan, not China, and I have been unable to find a preciose reference.

But I can offer this quote about the Zen priciples of wabi sabi:

Wabi-sabi is the quintessential Japanese aesthetic. It is a beauty of things imperfect, impermanent, and incomplete. It is a beauty of things modest and humble. It is a beauty of things unconventional...
It is also two separate words, with related but different meanings. "Wabi" is the kind of perfect beauty that is seemingly-paradoxically caused by just the right kind of imperfection, such as an asymmetry in a ceramic bowl which reflects the handmade craftsmanship, as opposed to another bowl which is perfect, but soul-less and machine-made.

"Sabi" is the kind of beauty that can come only with age, such as the patina on a very old bronze statue.

Wabi and Sabi are independent word stems in normal speech. They are brought together only to make a point about aesthetics. Sabi is most often applied to physical artistic objects, not writing. A well-known examplar of what one would call a "wabishii" object: black spit polish boots with dust on them from the parade ground. Many Japanese pots, the expensive ones, are dark and mottled -- wabi. "Sabishii" is the normal word for "sad", as in, that was a sad movie.

A related term in literature and the arts is "clinamen", the act of deliberately breaking a stylistic rule to enhance the beauty of an otherwise perfect whole. "

From here.

More to follow if I can find it. The problem is in this notion of "imperfection".
