As one of the representatives of Chinese food culture,Huaiyang cuisine had made great prog-ress in the Ming and Qing Dynasties,and had become one of the"state banquets"from the local cuisine.Huai-yang cuisine developed in the Ming and Qing dynasties due to a number of factors,in which consumers,main-ly Jiangnan literati,merchants and gourmets,played an important role.On the one hand,the Grand Canal pro-moted the development of Huaian and Yangzhou in the Ming and Qing dynasties,and the prosperous urban economy and material circulation laid a material foundation for Huaiyang cuisine.On the other hand,in the Ming and Qing dynasties,Jiangnan intellectuals took pleasure and material pursuit as their philosophy of life,which provided ideological preparation for the development of Huaiyang cuisine.On this basis,the literators and scholars in Huaiyang region promoted the development of Huaiyang cuisine to"delicacy"by feasting at poetry fairs,while the salt merchants in the region promoted the"luxury"aspect of Huaiyang cuisine by com-paring and showing off.Finally,during the Ming and Qing dynasties,a large number of gourmets such as Yu-an Mei appeared in Huaiyang area,which promoted the theorization of Huaiyang cuisine from the height of food philosophy,thus promoting the inheritance and development of Huaiyang cuisine in the Ming and Qing dynasties.Therefore,Huaiyang cuisine did not become obscure due to the decline of the Grand Canal,but sur-passed local restrictions to become a national cuisine.This provides ideas for food cultural heritage protection.
