First, change your heart for the truth.
If you want to make real friends, you must pay sincerely. Always stand in each other's position, think of others, do everything and say everything from the heart for the benefit of friends. As the saying goes, after a long time, people will be moved by your sincerity.
Second, a friend in need is a friend indeed.
A true friend is not someone who appears by your side when you are in prosperity, but someone who stands by and gives you a helping hand, comforts you and encourages you when you are in adversity. Similarly, when a friend is in trouble and needs help, you should give support at the first time, even if it is just a few words of comfort, it is as warm as timely help.
Third, learn to be tolerant
There will inevitably be frictions and misunderstandings between people, so we should learn to be strict with ourselves and be lenient with others. Laugh at some unimportant things, be frank when you disagree, listen to what the other party says and fully understand.
