Research depends on "light steps and deep footprints" ■ Ma Xiaojun A department pays attention to the scientific evaluation of leading cadres' grassroots research, which depends on both the research style and the effectiveness of the research. In this regard, they have a visual summary: research should be "light footstep, deep footprint". Investigation and research is a good tradition of our party and army. It is not easy to do a good job in investigation and research. For leading cadres, if they have a good style of work, they need to work hard to produce satisfactory research results. Light footed, reflecting the research style. Research is not inspection and guidance, but open-door consultation, brainstorming, learning from officers and soldiers with an open mind and asking for advice from the grass-roots level. If we repeatedly get together and mobilize the masses, it will not only be difficult to hear the truth, but also disgust the grass-roots officers and soldiers. The footprints are deep, reflecting the research results. Research is not a superficial observation, but to find and solve problems. If you run a lot of points and spend a lot of time, but always float on the surface, unwilling to work hard to "dissect sparrows", and do not master the first-hand situation, it is not called real investigation and research. Research is a regular work. Only by adhering to the principle of "light footsteps, deep footprints", listening to the truth, exploring the truth and learning from the truth, translating the research results into ideas and methods in a timely manner, and effectively solving the practical problems in war preparation, transformation and construction, and emerging fields, can leading cadres win the recognition of officers and soldiers and promote the continuous progress of the cause of building a strong military in the new era.
