Abstract: The merchants of Jin (modern Shanxi Province) had great influence in the Ming and Qing dynasties (1368-1911). In the process of market development, Shanxi merchants not only played a role in economic communication, but also brought Shanxi culture and even Han culture to other regions and peoples, greatly promoting cultural exchanges between Regions and nationalities. The exchange of dietetic culture is an important expression of cultural exchange. The Mongolian region of Tumed is an important trading area for the Jin merchants. The study of the interaction between the activities of the merchants from Mongolia and Jin in this area and the changes of the diet culture can help us better understand the role of Jin merchants in the communication between regions to provide resources for exploring the friendly communication between the Mongolian and the Han.

Key words: Jin merchant, cultural exchange, diet, Tumed Mongolia
