The importance of national security:

National perspective: National security is an important guarantee for national survival and development. Only when national security is guaranteed can the economy and society develop continuously and the motherland become more prosperous and strong.

People's perspective: national security is the premise of people's happiness and well-being. Only when the country is stable can we have a good study environment, a good production and living environment, safe life and property, a sense of security, a better life and a better future.

It is conducive to improving the legal awareness of the government and the public in safeguarding national security. Through a series of activities on the National Security Education Day, the government and the public can effectively understand the requirements put forward by the national security law, thus enhancing their sense of responsibility. It is to concentrate on disseminating national security knowledge to the public, which is conducive to a good publicity effect in a short time, so that more people can understand the legal knowledge of national security, especially how to perform their duties and obligations of safeguarding national security according to law.
