Abstract: Tourism flow accelerates the communication between people, and then speeds up the integration and innovation of multiple cultures, thus constituting a new connection in terms of cultural significance. Food, as a cultural symbol of a specific society, forms a “spatial community” in line with local cultural expression and tourists’ identity in tourism flow. From the perspective of tourism flow, this paper analyzes the community consciousness of the Chinese nation and its structure level contained in the “Long Street Banquet” of the Hani people in Yunnan Province. The study finds that tourism flows break down the traditional cultural logic of “man and God” and “man and man” of the “Long Street Banquet” into four levels–a historical narrative with the common cultural identity of China, “green, ecological and safe” material, the spirit of promoting power, and the society in which all ethnic groups eat together. In other words, from the structural level, the “Long Street Banquet” in tourism flow realizes the identity of all levels in the relationship of interaction and integration of the host and the guest, and finally manifests itself as the base level of “I” identity, the advanced level of “others” identity, and the integration level of “Chinese nation” identity.

Key words: tourism flow, consciousness of community for the Chinese nation, Long Street Banquet
