President Xi Jinping pointed out during his inspection in Heilongjiang that the second batch of themed education has been launched, and various regions should adhere to scientific planning, overall arrangement, and classified guidance to ensure effectiveness. This important instruction specifically emphasizes "classification guidance". The process of classification guidance is a process from the surface to the inside, from the shallow to the deep. The more scientific the classification guidance is, the better it is to find the right target, train of thought, and find good methods. The second batch of themed education in the military involves a wide range of units and personnel, multiple types, and a large number, with more direct and close contact with officers and soldiers. The contradictions and problems faced are different, and it is even more necessary to provide classification guidance. Only by adhering to specific analysis of specific problems and treating different situations differently, can we achieve targeted treatment without going through motions. If classification guidance is not done well and one's eyebrows and beard are grasped, theme education cannot be targeted and it is difficult to achieve good practical results. Classification guidance is an important method for our party and army to carry out work, and it is also a guiding ideology that needs to be grasped to do a good job in the second batch of military themed education. Adhering to classified guidance, we must pay attention to starting from reality, distinguishing between different levels, fields, and objects such as combat forces, teaching and research institutions, national defense mobilization systems, and support units. We should make arrangements according to local conditions, scientifically and reasonably, improve organizational guidance methods, identify the focus and focus of their respective thematic education, refine standard requirements, and not adopt a one-size fits all approach, Promote the effective and orderly implementation of the second batch of themed education in the military.
