Social communication ability refers to the ability to properly handle the internal and external relations of the organization, including the ability to establish extensive contacts with the surrounding environment, absorb and transform external information, and correctly handle the relationship between the upper and lower sides. From a certain point of view, a good interpersonal relationship should be that individuals use the principles of honesty, tolerance and understanding in the process of interacting with others, establish their own good image, form a harmonious relationship in the collective, actively expand their own contacts, and constantly benefit others and gain social praise. Interpersonal communication ability is the ability to live in harmony with others in a group. People are social people. It is hard to imagine what a person's life would be like without society and communication with others. If someone exists, he must associate with others. When we go out into the society, we will deal with all kinds of people. Whether you can get others' support and help in dealing with people will involve your own ability. I think we should cultivate our ability to deal with classmates, teachers, leaders and employees during our study in school. When talking with classmates, you can debate on different academic viewpoints and different understandings of social phenomena, so as to improve your thinking ability in the debate; Talking with teachers can exchange reading experience, sort out different ideas and understandings, and get inspiration from them; Talking with leaders can fully exchange their different views on the problem, and perhaps exercise themselves not to get stage fright in front of leaders; When dealing with employees, we can understand their working status and different mentality. Be good at communicating with people, and you will learn a lot from it that books can't. Young college students are active in thinking and rich in feelings, and have a strong demand for interpersonal communication. Everyone is eager for sincere friendship, and everyone tries to gain friendship through interpersonal communication to meet their material and spiritual needs. However, in the face of new environment, new objects and tense study life, some students' psychological contradictions have intensified. At this time, positive interpersonal communication and good interpersonal relationship can make people feel happy, full of emotions, full of confidence and maintain an optimistic attitude towards life. Generally speaking, most students with good interpersonal relationships can maintain cheerful personality and warm and optimistic quality, so as to correctly understand and treat various practical problems, resolve various contradictions in their study and life, form positive and excellent quality, and quickly adapt to college life. On the contrary, if you lack positive interpersonal communication, can't treat yourself and others correctly, and are narrow-minded and short-sighted, it is easy to form great mental and psychological pressure, and psychological contradictions are difficult to resolve. Seriously, it may also lead to morbid psychology. If you don't dredge it in time, it may form a vicious circle and seriously affect your physical and mental health. College students are filled with emotion. After intense study, they need to communicate with each other, discuss their ideals and lives, and tell their joys and sorrows. Interpersonal communication is the best way to realize this desire. Through interpersonal communication, we can meet the needs of college students for friendship, belonging and security, realize their value in the collective more deeply and vividly, and produce a sense of intimacy and attachment to the collective and others, so as to obtain a full and happy spiritual life and promote physical and mental health. Interpersonal communication is an important way to exchange information and acquire knowledge. Modern society is an information society, and the quantity and value of information are unprecedented. With the expansion of information, people have higher and higher requirements for owning and using all kinds of information. Through interpersonal communication, we can exchange information and achievements, enrich our experience, broaden our horizons, activate our thinking and enlighten our thoughts. (2) International communication is an important means for individuals to know and improve themselves. Confucius once said, "Learning alone without friends is ignorance." Interpersonal communication can help us improve our understanding of ourselves and others. In the process of interpersonal communication, we know each other from their manners. At the same time, I learned about myself from each other's reaction and evaluation. The wider and deeper the communication, the more complete the understanding of the other party and the deeper the understanding of yourself. Only by fully understanding others and deeply understanding yourself can we get others' understanding, sympathy, care and help and achieve self-improvement. (3) Interpersonal communication is the need of collective growth and social development. Interpersonal communication is a link to coordinate collective relations and form collective strength. And a good group can promote the formation of excellent personality quality of young students. Such as sense of justice, compassion and optimism. They all grew up in democratic, harmonious and friendly interpersonal relationships. Good interpersonal relationships can also enhance students' cohesion and become the most important educational force in the collective. Interpersonal communication is the interaction between people. Good interpersonal skills are positive, on the contrary, it is not conducive to the all-round and healthy development of individuals. The core of interpersonal communication is cooperation and communication. To cultivate communication skills, we must first have a positive attitude, understand others and care about others. In daily communication activities, we should take the initiative to communicate with others, don't avoid passively, dare to contact, especially dare to face people different from ourselves, and don't be afraid of birth, appearance and experience. Don't shut yourself off just because they come from remote areas, and don't shut yourself off just because they are ugly or less experienced than others. Secondly, we should start from an early age and pay attention to social etiquette. Thirdly, we should be good at doing things, boldly go out of school, eliminate fear, strengthen knowledge accumulation in communication, experience in actual communication life, and master various methods and skills in interpersonal communication. In addition, we should realize that in dealing with people, what is touching is sincerity, sincerity in making friends, sincerity in doing things, and sincerity can be exchanged for cooperation and communication with people. Sincerity is always one of the most precious feelings of human beings. In fact, the master of everyone's life is himself. The key is to change and have a strong desire for success. We hope that through the understanding and understanding of the characteristics and principles of interpersonal communication, we can let everyone know some knowledge of communication. Combining these characteristics and principles, we can find suitable ways to cultivate our interpersonal skills and promote our own interpersonal relationships. Let those students who are unwilling, ignorant and unsociable in life, study and work shape their own image, treat interpersonal communication with positive attitude and behavior, and establish harmonious interpersonal relationships.
