The most important purpose of carrying out the theme activities of National Security Education Day is to raise people's awareness of national security. The author believes that countries often face double pressures. Externally, it faces problems of national security, sovereignty and development security, and internally, it faces problems of social stability, harmony and political security. Faced with these two problems, the people of the whole country should unify their thinking and pace and work together to safeguard national interests and national security. Everyone must make a contribution to this issue, in order to gather sand into a tower and cast the motherland into an unbreakable Great Wall of steel. For this kind of activity, the author is very supportive and in favor. It is very necessary to hold this theme activity, which can unify thoughts and raise awareness. It also reflects the country's emphasis on national security. The theme activities will be carried out smoothly and successfully.

In addition to raising people's awareness of national security, there are also these meanings: raising people's understanding of relevant laws, enhancing national honor, and strengthening people's mobilization. The following details these three points:

1. This activity can raise people's legal awareness: in fact, there are quite a few laws and regulations on national security, such as the Anti-Spy Law, the Cyber Security Law and the National Security Law. Through the publicity of this activity, people can avoid unintentionally breaking these laws, and they can also shock those who want to harm them through publicity.

2. This activity can increase the sense of national honor: when the people of the whole country are working hard for national security, they actually inject more emotions into these activities, which is patriotic feelings, so this theme activity is used to increase people's patriotic feelings.

3. This activity can strengthen people's mobilization: in ordinary daily life, people rarely think and go back to do things related to national security, but this activity is actually a general mobilization of people. By establishing the concept of national security, people are further encouraged to actively participate in relevant actions to safeguard national security, so this activity has played a very good mobilization role.
