Douyin short videos provide users with a new interaction scene, and the social atmosphere is the emotional element in the scene. Douyin focuses on the establishment of the relationship between the photographer and the viewer, and allows users to have real-time social feelings by double-clicking on interactive mechanisms such as likes, comments, and reposts. The broadcast video interacts, and the video is captured for feedback, forming a closed loop for the broadcast, which enhances the user stickiness of the vibrato. Douyin also pays attention to the connection with other social platforms, and encourages users to forward the video to Weibo, WeChat circle of friends, Meipai, etc., to promote the secondary transmission of the video and meet the social needs of users. The feature of the Douyin circle also helps users to feel a sense of belonging, which stimulates social behavior.
