It points out and illuminates the future direction of China's domestic news and public opinion work, and provides fundamental principles for it. In the face of novel coronavirus pneumonia outbreak and other public emergencies, the role of party media in guiding public opinion is very important. We must pay attention to content and pay attention to communication strategies to better play a guiding role.
