Abstract: Focusing on the practical manifestations of sociological interaction and ritual theory, this paper conducts a theoretical
exploration. It centers on the era theme of forging a strong sense of community for the Chinese nation and conducts an extended
consideration. It also conducts a logical analysis on the cultural and spiritual values contained in the consumption behavior of the Buyiethnic group in a regional context. Based on the Marxist economic principles of "production, distribution, exchange, and consumption", a reverse consultation is carried out to examine the functions and values of each link of "production, distribution, and exchange" from the perspective of "consumption". Through the study of the consumption interaction and ritual manifestations of the Buyi ethnic group in the third local dialect region of Guizhou, this paper examines the theory and practice of their "three interactions" with other ethnic groups. It conducts a logical examination from four dimensions: register and argument, presence and inspection, interaction and cognition, practice and prospect.

Key words: interaction and ritual, consumer culture, communication, exchanges, and integration, practice and theory, the third local
