In view of the instability of international relations and the increasingly prominent issue of regional sovereignty, it is necessary and far-reaching to strengthen national defense education for primary school students. So how can we strengthen national defense education in rural primary and secondary schools? First of all, as an education manager, we should have advanced national defense consciousness. In organizing school education and teaching activities, national defense education should not be put in the last place, but should be regarded as an important course in our curriculum arrangement, with at least one class hour arranged every week and new teaching content every week. Secondly, we should strengthen the education of students' national defense dynamics. Let students know about national defense knowledge in time and enhance their sense of crisis and responsibility. As a school education under the new situation, students are not only required to have a firm grasp of knowledge, but also to be branded as "I am a citizen of China, and I want to defend the motherland" from an early age, and to establish a sense of patriotism from an early age, knowing that their territorial sovereignty includes Taiwan Province Province and the whole South China Sea. I have known since I was a child that the recovery of these areas still faces challenges from many Asian neighbors, such as the Philippines, Vietnam and Japan, and is encouraged by the United States, Britain, France and other western countries.
