1 first of all, we must establish the range of making friends, that is to say, what kind of people can develop into friends and what kind of people can't develop into friends. Honest, friendly and aboveboard people can develop into friends, because you can help each other, advance hand in hand, and move towards the bright road; People who don't distinguish between good and evil and are mercenary should stay away, because they can only bring you trouble, fool you and even lead you to the abyss of crime. Secondly, you must have the right attitude when making friends. What do you make friends for? Not for your endless demands on others. If you don't pay a little in return for others, you can't make real friends. If you find someone who can be friends, you should cherish the feelings between friends. The principle of making friends is quality, not quantity, but "sincerity" is the key to treating friends.

2. Treat friends sincerely. Making friends is heart, not profit, so communicate with your heart. Sincerity is not only the basic principle of being a man, but also the fundamental principle of getting along with friends. Because it is not easy to make friends who really know each other and can communicate for a long time. Only by treating others sincerely and giving true feelings can we reap the seeds of friendship and gain more friends. Meng said well: "Don't be long, don't be expensive, and don't be friends with brothers. Friends are friends, and friends are virtuous. There can be no shackles. "
