Confucius believed that food was not just about nourishment but about harmony, balance, and social order. He emphasized the importance of proper dining etiquette, such as not eating before one's elders and using chopsticks correctly.

The great migration of Chinese people south during the invasions preceding and during the Song dynasty significantly increased the relative importance of southern Chinese staples such as rice and congee.

This movement also led to the development of new culinary techniques and dishes that catered to the local climate and available ingredients.
Spanish and Portuguese traders began introducing foods from the New World to China through the port cities of Canton and Macau.

During the Qing dynasty, the most praised Four Great Traditions in Chinese cuisine were Chuan, Lu, Yue, and Huaiyang, representing cuisines of West, North, South, and East China, respectively.

These regional cuisines are distinguished by their unique ingredients, cooking techniques, and flavor profiles, reflecting the diverse geography and history of China.
Chinese cuisine is deeply intertwined with traditional Chinese medicine, such as in the practice of Chinese food therapy. Color, scent, and taste are the three traditional aspects used to describe Chinese food, a standard that starts from the Tang dynasty in the 6th century by Bai Juyi from the Preface of Lychee Diagram. The philosophy behind it was rooted in the I Ching and Chinese traditional medicine, where food was judged for color, aroma, taste, and texture, and a good meal was expected to balance the Four Natures and the Five Tastes.
