National security is the foundation of the country. National security issues are related to national security and national survival, and to the vital interests of every citizen. On the one hand, national security is the premise of personal safety. Without national security, there can be no personal security. On the other hand, national security depends on the conscious maintenance of every citizen. Therefore, it is the sacred duty of every citizen to safeguard national interests and security. Under no circumstances should he do anything that endangers national security, but he should consciously fight against all acts that endanger national security. Article 54 of China's Constitution and Article 3 of the National Security Law clearly stipulate: "People's Republic of China (PRC) citizens have the obligation to safeguard national security, honor and interests, and may not commit acts that endanger the security, honor and interests of the motherland." As college students in China in the 2 1 century, it is an unshirkable responsibility to safeguard national security, and it is also the basic requirement of the party and the state for every college student. In today's increasingly complex national security issues, college students must enhance their awareness of national security, learn the legal knowledge of national security, earnestly fulfill their legal obligations to safeguard national security, and become conscious defenders of national security and interests.
