Chen Yixin, Secretary of the Party Committee and Minister of the Ministry, has conducted in-depth research in national security agencies in Beijing, Guangdong, Tianjin and other provinces and cities. Each Party Committee member of the Ministry has selected at least one second batch of theme education units for on-site research, conveying the relevant spiritual requirements of the Party Central Committee, understanding the progress of theme education, discovering and promoting work experience, promptly pointing out problems and deficiencies, and helping to solve practical difficulties. Under the demonstration and guidance of the Party Committee of the Ministry of National Security, various departments and units have taken action, from the Qinghai Tibet Plateau to the southeast coast, from border ports to the hinterland of the Central Plains, and in the vivid practice of "four grassroots", continuously promoting the use of learning to cast the soul, increase intelligence, correct the style, and promote work, achieving tangible results. In Guangdong, Chen Yixin participated in the theme party day activity of the grassroots party branch he contacted, and gave a "micro party lesson" to inspire and inspire frontline police officers around promoting the improvement of the "five qualities" of police officers through grassroots party building. The main leaders of Tianjin Municipal Bureau set up "Overall National Security Concept Classrooms" in various grassroots bureaus, focusing on the location advantages and local industrial resource characteristics of grassroots bureaus, and providing targeted explanations on the practical requirements of non-traditional security. The Shaanxi Provincial Department has established a "door-to-door teaching delivery" mechanism, and the members of the Party Committee of the Department will provide face-to-face explanations and hands-on teaching on the implementation of various decision-making and deployment ideas and measures in their respective fields. The Yunnan Provincial Department held a special seminar on enhancing political capabilities among "top leaders" at all levels, allowing them to bring back the new spirit and requirements of the Party Central Committee and the new deployment and new concepts of the Party committees to the forefront through learning and understanding. Promoting the transformation of research results at the grassroots level, national security agencies are implementing the principles of "accelerating the transformation speed of research results" and "increasing the intensity of problem rectification", and focusing on promoting development in connecting with the grassroots level. In Beijing and Tianjin, Chen Yixin conducted in-depth research and guided the implementation of key work tasks of national security agencies, injecting strong momentum into the pursuit of annual work goals and tasks. The leadership of the Party Committee of the Xizang District Office went to the grass-roots bureaus to carry out supervised research and "centralized consultation" on two groups of problems that need to be jointly rectified in thematic education to ensure that "everything is implemented and everything is answered". The Hunan Provincial Department focuses on prominent issues such as insufficient resource integration and poor supply-demand relations reported by grassroots units, formulates an implementation plan for enhancing the integration of scientific and technological resources throughout the department, and fully utilizes the innovative mechanism of "virtual banking" to empower grassroots police officers in practical combat. The Jiangxi Provincial Department adheres to the clear guidance of "all towards war, all for war", regards grassroots contact points as "experimental fields" and "training grounds", promotes the actual combat forces of the Provincial Department to sink to the grassroots, and implements "bundled operations".
