Chinese-art.com has two separate sections of which the other one
concentrates on contemporary Chinese art. You can also visit our page
titled "Cultural and Regional Aesthetics" and see if our collection of
links are of use. There's also an article titled "Introduction to
Chinese Art and Aesthetics" by Prof. Dusan Pajin - that might be of
interest to you as well.
Here's the link for the cultural views on aesthetics:
