In 2016，the mobile networks and applications played a key role in the formation and fermentation of public opinion in China. Both Weibo and WeChat attracted more users. The value of public opinion on mobile networks as well as the diversity of news APPs increased. The mobile live video streaming started to bloom，and the “peripheral zone” of online public opinion，such as Q & A applications，caused wider concern. The public opinion dissemination and agenda setting showed new features. The words related to the mobile networks governance such as “regulation and governance of internet in accordance with the law”，“online mass line”，“government response to public opinion online”，“spreading positive energy” became popular.
