As a new platform for young people to explore, discover and share beautiful lives, Tik Tok has the magic power to popularize tourism destination. People record their travel on Tik Tok, and they share similar experiences and emotions with others who have the same emotional values after they confirm their identity tags and enhance their self-and group-recognition through interactions with other tourists. This research, illuminated by the phenomenon of Tik Tok pushing tourism destinations to mass popularity, takes Xi’an, capital of Shaanxi, a northwestern province in China, as a case to discuss the construction of identity on Tik Tok among modern tourists, interpret the tourism mode with different tags oriented by emotional values among modern tourists, and further apply tribalism to tourism study, from the perspective of tribalism and reference to the division of identity structure – cognition, emotion, and behavior – from Zhang Shuhua(2012). In addition, the research patterns and results are boons to the market subdivision of tourism destination marketing under the new perspectives, the identification of tourist groups with different interests, the shaping of tourism products that suit their tags, the creation of the emotional atmosphere, and the original ideas for accurate and effective marketing planning of tourism destination.
