With the rich resources of Jianshui food culture in southern Yunnan，the food tradition and ethnic minority food customs under the influence of the Han culture have been formed. The food culture presents the characteristics of “each has its own beauty and each place has its own diversity”. The steam pot，steam pot chicken and other delicious food carry the memory of food culture. The activation of food cultural memory as well as the re-excavation and reuse of food cultural resources have promoted the restoration of the style of the ancient city，the construction of creative blocks，rural construction and the development of cultural tourism，making tourists immersed in the nostalgic journey of food culture. The “City of Food” is the direction of cultural inheritance and construction of cuisine in Jianshui. The government，enterprises and society should be mobilized to take active action，utilize the opportunity of developing nostalgic food with regional culture to achieve high-quality development of the catering industry and cultural tourism industry and urban transformation and upgrading in Jianshui.
