Civil air defense knowledge education is an important part of national defense education, an important part of patriotism and life education in schools, and a strategic project of "teaching for life". Carrying out civil air defense knowledge education can enhance young students' awareness of national defense and hardship, stimulate students' patriotic enthusiasm, enhance students' sense of mission and responsibility, improve students' ability to deal with various emergencies, exercise their healthy psychology in the face of danger and improve their quality of life. At the same time, it is also conducive to cultivating students' organizational, discipline and moral quality, broadening students' knowledge horizons, improving students' knowledge structure, promoting students' all-round development in morality, intelligence, physique and beauty, and cultivating and bringing up useful talents for the construction of Socialism with Chinese characteristics. Education bureaus, civil air defense offices and middle schools at all levels under the jurisdiction of cities (districts) should do a good job in the education and popularization of civil air defense knowledge among middle school students with a high sense of political responsibility.
