We has witnessed how the outbreak of COVID-19 has accelerated the arrival of the digital era in 2020. Since 2020，the spread of trending events has shown new features. First，the pattern of narratives on the Internet public opinion field has become diversified and stratified. Second，narratives on significant development issues remain to play the dominant role，while the integration of online and offline governance and the linkage of domestic and international propaganda have become a new trend. The public opinion field has concentrated on public events about people’s livelihood，enterprises，international affairs，science，and public health. Meanwhile，the platforms providing live streaming and short videos have become an increasingly essential source to expose social issues and ignite public discussions. In the future，the digital government，the official social media，the digital transformations of enterprises，and the emergence of new occupations will boost the construction of a digital society in China，while problems on data security，digital divide，and international communication remain to be resolved.
