The National Security Education Day is an important measure set up by the China Municipal Government, aiming at raising people's awareness and understanding of national security. There are several important background factors behind this move. First of all, national security is the fundamental interest and premise of a country. Facing the increasingly complex and changeable international environment and various security threats, it is very important to ensure national security. Through the establishment of National Security Education Day, people's understanding and cognition of the national security situation can be strengthened, and people's safety awareness and self-protection ability can be improved. Secondly, the arrival of the new media era makes information dissemination more rapid and extensive. In this era of information explosion, the popularity and use of various information channels make safety awareness education more important. The establishment of the National Safety Education Day provides an opportunity for the government to focus on publicity, education and training, spread safety knowledge and skills to the whole society through various media platforms, and strengthen the wide coverage of safety education. Finally, the National Security Education Day also emphasized the importance of national security work and the importance of national participation. Maintaining national security is the common responsibility of the whole society. Only through extensive safety education can everyone realize their responsibilities and obligations and form a strong sense of national security and social consensus.
