In the audience of online games, a large part are teenagers, even children. How to reduce the disadvantages of online games and expand their positive significance has become a topic of concern to UNICEF. German educator Winfield Kaminsk believes that online games will not affect children's growth, and all kinds of criticisms about children playing games for a long time are caused by prejudice. Kaminsk, an expert at the Cologne Institute of Media Studies and Media Education, said: "The prejudice against children playing games is repeated and reflected in every generation. The reason is that it is always difficult for children to get their parents' understanding of what they are concerned about. In fact, today's children's ability is to concentrate on playing a computer game for a long time and obey several rules. Online games usually require children to' play their own role and write their own history' within a few months. " I believe that as long as the content of online games is healthy and the connotation is positive, it will not bring "harm" to children, but will give them some ideological education.
