Yi Yin, a minister in the early Shang Dynasty. Before taking office, I worked in Xinting area of our county. "Mencius" records: "Yi Yin cultivated the wild and enjoyed the way of Yao and Shun". Yi Yin, a veteran of the Five Dynasties of Shang Dynasty, assisted Shang Tang, Waibing, Ren Zhong, Tang Suntaijia and Woding for more than 60 years. He ruled the country well and was in power for a while, which laid the foundation for the inheritance of the Shang Dynasty for 600 years. Yi Yin was the first prime minister and the first emperor's teacher recorded in the history of China, and was called a "saint" by Mencius. At the same time, Yi Yin is also praised as "the originator of cooking" and "the chef saint" by the culinary circles in China.

Yi Yin's Banquet for Governing the Country and Keeping Healthy captures Yi Yin's three concepts of governing the country, keeping healthy and keeping healthy. Yi Yin analyzed the general trend of the world and the way of governing the country, advocated "honesty above, loyalty below", and paid attention to respecting the virtuous and using the virtuous. "Governing a big country is like cooking a little fresh food" is a high praise for him. Tang laid the foundation for the development of dietotherapy and health preservation theory in later generations. Yi Yin's cooking theory, such as the harmony of five flavors, has always been used in court food codes of past dynasties. This banquet not only embodies the diet health culture in Yi Yin period, but also embodies Yi Yin's thought of governing the country, which is a vivid representation of ancient diet health.
