Information release is an important part of China’s Fight against the COVID-19. A strict system of information release has been established. Strict regulations are in place to see there is no withholding of information，underreporting，or delay in reporting cases of infection. Meanwhile，a tiered news release mechanism has been formed. At both national and local levels，a tiered information release mechanism has been formed to circulate authoritative information through various channels and platforms，both onsite and online，in order to address domestic and international concerns on virus control，medical treatment，and scientific research. The media has expanded public outreach and sent a positive message in combating the virus，and public opinion has played its role of oversight to help solve problems affecting virus control. Of course，looking back on this battle to prevent and control COVID-19 pandemic，we find that the public opinion environment is extremely complex. Therefore，it is of very important values to analyze these problems and put forward proposals.
