Abstract: In the prevalent network culture, the phenomenon of "keyboard man" is quite common. Teenagers are in the key period of growth, and the influence of this phenomenon on dispelling the mainstream values of teenagers, impacting the network morals, disrupting the normal network order, and promoting the dual personality of teenagers, cannot be underestimated. The reasons for this phenomenon from the perspective of ideological and political education are the ineffective guide of values education, the weak media literacy education, the insufficient counseling for rational understanding, and education incoherence. Reliable strategies to deal with the problem of "keyboard man" are playing the "main melody" of values education, linking up the "main channel" of media literacy education, opening up the "intersection" of emotional and rational education, and outlining the "concentric circles" of tripartite collaborative education.

Key words: teenagers, keyboard man, ideological and political education, mainstream values
