On the occasion of the National Security Education Day for All, the National Security College of the National Defense University has leveraged its disciplinary advantages to organize multiple teaching teams to conduct "door-to-door teaching" activities in the military, bridging the "last mile" of theoretical services for the military, as the current world is undergoing unprecedented changes, with traditional and non-traditional security threats intertwined and overlapping. At the critical stage of the start of the 15th Five Year Plan, the mission of coordinating development and security, safeguarding national sovereignty, security, and development interests is becoming increasingly arduous. In recent years, the college has deeply implemented the overall national security concept, focusing on the construction of national security as a first level discipline under interdisciplinary categories, providing solid talent and intellectual support for building a strong national security barrier and serving the cause of building a strong country and military. Recently, Professor Meng Xiangqing from the college visited the Western Theater Command to deeply interpret the current international strategic situation and China's surrounding security environment around the overall national security concept. Professor Li Guoting led the teaching team to go deep into the border guard post, providing theoretical guidance to officers and soldiers face-to-face, guiding them to strengthen their mission and responsibility from the perspective of national security strategy. Standing on the front line of border defense, the posts are connected to national security and people's happiness. We will definitely shoulder our responsibilities and missions, continuously improve our ability to win, and defend the sacred territory of our motherland, "said Liu Jie, the squad leader of a certain unit, firmly after listening to the lecture on site. Next, the college will continue to leverage its disciplinary and faculty advantages, coordinate high-quality teaching resources, provide theoretical guidance to frontline troops on border islands, continuously expand educational coverage and improve educational effectiveness, and use high-quality theoretical services to help build a strong national security barrier and provide strong support for the cause of strengthening the military. The 71st Group Army's certain brigade, in conjunction with its stationed training tasks, has built a strong security defense line. National security classroom entry and formation. "Field stationed training cannot become a safety blind spot. The more dynamic and dispersed it is, the more we must guard the bottom line! ”Recently, a statement made by Zhu Bo, an instructor from a certain brigade and battalion of the 71st Group Army where Wang Jie was serving before his death, at a security situation analysis meeting in the training area resonated with the officers and soldiers. Faced with the multiple risks brought by intensive training tasks, scattered locations, and frequent use of networks, the brigade has established multiple lines of defense, including institutional control and technical protection, to strengthen the safety barrier for field training. The leader of the brigade introduced that they have integrated the study of national security laws, regulations, and policy documents into the "Sending Laws to Grassroots" activity, focusing on the needs of officers and soldiers for internet use and the practical management of grassroots level, guiding officers and soldiers to enhance their awareness of national security. At the same time, they apply lightweight, low-power, and easy to deploy technological protection measures to solve the problem of network security control under dynamic conditions, promote security prevention work throughout the entire training process, cover all officers and soldiers, and implement it at every combat position. At a certain training site, officers and soldiers held discussions and exchanges on "what are the security risks around us and how to maintain the bottom line of security", deepening their understanding of national security, and actively investigating hidden risks such as hidden leaks of intelligent devices on the front line of training. Nowadays, when using mobile phones, we pay extra attention to software with location functions and network links from unknown sources, "said class monitor Wang Yusheng. There are no bystanders in safety work, everyone is a safety officer. The various battalions of the brigade will also extend the national security classroom to the squad positions and motor vehicles, and carry out activities such as safety knowledge quizzes and demonstrations on preventing network traps. As a descendant of Wang Jie, only by shouldering the responsibility of safety and placing it on the battlefield can we add glory to the heroic collective, "said Second Class Sergeant Cao Mengxuan.

The sitcom "Secret that Cannot be Told" is based on the true story of the hidden front, vividly depicting the red history of our ancestors who went incognito and silently devoted themselves. This safety education class has both theoretical depth and practical depth. ”Li Zhuang, a cadre of Hengyang Garrison District, said that maintaining national security is the responsibility of soldiers.
