At present, a group of leading cadres have gone deep into the grassroots and entered the ranks of officers and soldiers, actively carrying out investigation work, and have found the truth and obtained the truth. On this basis, leading cadres should also deepen research to prevent excessive investigation and insufficient analysis of situations, and ensure that the proposed countermeasures and suggestions truly stand the test of practice. The many new situations and problems faced by the grassroots not only require us to delve deeper and understand the actual situation accurately, but also require us to concentrate on the materials and situations obtained from the investigation, and to conduct research and analysis from one to another, from the surface to the inside, to find the crux of the problem and come up with effective ideas and methods. If we only investigate without studying, we will see only trees but not forests. In practical work, a few leading cadres still have phenomena such as research disconnection, heavy emphasis on research and neglect of research, and even transfer without research. If these problems are not solved, it will be difficult to see the essence, study the rules, and find accurate countermeasures, and the effectiveness of investigation and research will also be greatly compromised. Leading cadres at all levels should adhere to the principle of emphasizing both investigation and research, not only understanding the truth and mastering first-hand information, but also putting in a lot of hard work, deep work, and meticulous research. In this way, we can improve the quality and efficiency of research, promote problem-solving with solid results, and promote the development of unit construction. (Outlook New Era Network)
