This may have something to do with your personality. If you are cheerful, lively and modest, and don't like to quarrel with others, like this, your interpersonal relationship will be very good.
Below I have several ways to deal with interpersonal relationships. First, be modest and prudent, which requires you to pay attention to details in your daily life and pay attention to places that others can't notice. This requires you to treat others with true feelings. Second, tolerance is the most lacking virtue in our life and in our country. We will only try our best to tolerate ourselves, but we will not think of tolerating others. Tolerance does not mean weakness, but generosity. When others make mistakes, it also shows your noble character. Tolerance is a kind of strength. When you can use this power maturely, you will become very powerful. Third, helping others, helping others is helping yourself. You can't live without others. One more friend means one more way. When you see someone in trouble, extend your hand to help him. Maybe you'll thank yourself later. Fourth, understand that everyone has their own difficulties. Don't be angry when you meet your friends and do something you can't understand. Understand the source of the problem, ask your friends, and don't take it on yourself.
Sometimes it's not that we have changed, but that society is too cruel. We should learn to be considerate of others, make good friends, take part in more public activities, be cheerful every day and make friends that won't harm you. We can help you when you are in trouble, enlighten you and find ways to help you. At the critical moment, we can do anything for our brothers.
