In ancient Chinese philosophy, the phrases "yīn" and "yáng" explain the fundamental rotation of the wheel of the universe. Accordingly, everything in existence derives its meaning from its opposite, and these forces are in a constant state of change and interplay. This philosophy of opposition and harmony extends even to Chinese cuisine. In cooking, some ingredients are believed to have a "cold" nature, while others are "hot," and they must be balanced. It’s common to find dishes that are both sour and sweet, or spicy and sweet, reflecting this blend of opposites.
