Under the background of increasingly prosperous social media, online socialization has gradually become an important way of socializing between people. Compared with the traditional "face-to-face" socialization, online socialization is favored by young people because of its invisibility, convenience and other outstanding advantages. The "invisibility" behind the anonymization of the network allows young people to immerse themselves in multiple role-plays on the network platform, realize the presentation of their self-image, and form a unique digital identity construction, and the phenomenon of "social anxiety on the network" has gradually come to the forefront, and poses a challenge to the creation of a harmonious social environment. The phenomenon of "online social anxiety" is gradually emerging and poses a challenge to the creation of a harmonious social environment. The reason why "stealth" has become a social phenomenon cannot be separated from the promotion of economic and social, cultural and psychological conditions. In this paper, we intend to interpret the psychological motivation behind "stealth" from the perspective of communication psychology, combining Maslow's need theory and classical communication theories such as compensation psychology, herd psychology, social anxiety, etc., and taking the social content of microblogging as the research object.
