Whether the relationship between officers and soldiers is good or not depends on the military leader. Only competent military leaders can bring out troops that are full of righteousness, vitality, and warmth. As President Xi emphasized, it is necessary to study and grasp the characteristics and laws of military leadership in the new situation, sincerely care for officers and soldiers, cultivate and guide officers and soldiers, wrestle and train officers and soldiers, and enable them to grow and progress in the military camp. Respecting cadres, loving soldiers, and being consistent with officers and soldiers is the fundamental principle and glorious tradition of our army. At present, in grassroots troops, issues such as physical punishment, eating and taking cards, and "micro corruption" have been effectively corrected. However, there are still varying degrees of issues with the lack of deep or genuine relationships between officers and soldiers: more work meetings, less ideological meetings, more emphasis on disciplinary regulations, less emotional communication, more politeness, and less confidences. One important reason is that individual military leaders have "superficial" knowledge of the military, "low-level" love for the military, and "paternalistic" military leadership. If these problems are not solved, we cannot manage combat effectiveness, regularization, and good work style, and we cannot bring out elite troops. Marshal Ye Jianying once said, "If you can lead and train your soldiers well in peacetime, you can use them freely and win battles in wartime. The three are interrelated, and the leadership is the first, but it should be implemented in the use of soldiers. When the soldiers lead well, you can talk about the training and use of soldiers." Some leaders can't talk with soldiers, play together, fight together, or know nothing about soldiers when they are in the army. These phenomena can't be regarded as trivial matters, It should be regarded as a major event related to the cohesion and combat effectiveness of the troops. A military leader with "light in the eyes and love in the heart" can view the soldiers of the new era with a perspective of trust, appreciation, and development. This will continuously enhance the scientific and effective effectiveness of military leadership, and diligently educate, guide, and shape soldiers with heart and emotion. Leading thousands of soldiers is the first way to know a soldier. Knowing soldiers is the foundation of leading troops, and without knowing soldiers, it is impossible to lead soldiers well. Familiarizing oneself with soldiers, understanding them, and continuously improving one's' knowledge of soldiers' is a prerequisite for leading troops, and it is also an inherent requirement for a close relationship between officers and soldiers. However, in the face of the characteristics of young soldiers such as hidden ideological issues, hierarchical interpersonal communication, and networked daily behavior, some military leaders do not have a high level of knowledge about soldiers. They often know one thing and two things, the surface and the inside, and the reason for knowing it. Knowing soldiers requires sincerity. As a military leader with "light in the eyes and love in the heart", one should have a comprehensive and multi-level understanding of the soldiers' situation, not only knowing the soldiers' file materials, but also the actual situation of the soldiers; Not only should we know what is' external ', but also what is' hidden within'; Not only do we need to know where the soldiers are and what they are doing, but we also need to know what they are thinking and hoping for; Not only do you need to know what the problem is, but you also need to know why. We should not only be good at "face-to-face", but also learn to "key to key", build a multi-dimensional "heart to heart bridge" of ideological resonance, spiritual resonance, and integration of words and actions, and actively integrate into the warrior's "circle of friends". For example, in the past, we used to talk about "activities based on interests, eating based on appetite, sleeping based on posture, and walking based on demeanor". Now, we need to "look at avatar changes, watch attention online, spend money based on direction, and chat based on emotions" to grasp the ideological pulse of soldiers from subtle aspects. Those who strive for victory will first love their soldiers
