In regions where there is a lot of migration and a number of ethnic groups, people often take advantage of political, economic and cultural resources to blend the practices of different ethnic groups and re-create their food and foodways. Among the Yi people of Liangshan in southwest China, a new kind of ”Yi cuisine” has appeared, based on the traditional foodways of the Yi. Some of these ”Yi-style dishes” show signs of influence by the Han Chinese who came to this region later. Such phenomena are the result of cultural interaction arising from migration. This article examines the causes and effects of the emergence of these new ”Yi-style foods.” It also describes the traditional food of the Yi and the Han. The creation of new ”Yi-style dishes” can be said to reflect the transformation of the traditional foodways of the Yi, but also represents a local adaptation of Han Chinese foodways. At the same time, this represents a process of re-interpretation of Yi cultural identity.
