Chinese philosophy pays a great deal of attention to opposites. Light and dark, sad and happy, black and white. These concepts are called Yin and Yang. But these concepts are more than opposing. They are complimentary. There can be no light without dark, no dark without light. No heaven without earth, and no earth without heaven. This philosophy permeates all of Chinese culture, including their cuisine. The philosophy of Yin and Yang is represented in the familiar sweet and sour dishes in Chinese cuisine. The two flavors are opposite in the reactions and sensations they give the taste buds, but yet they also compliment each other, are both present in one dish to be savored separately and in combination with one another.
