Secondly, treating others sincerely is the basis for others to recognize and accept you. Obviously, a deceitful and treacherous person will not make sincere friends, but a sincere person is more likely to be respected and recognized by others.
Third, be strict with yourself and be lenient with others. When you disagree with other people's views, you can not accept their views, but you must respect their rights and personality. Everyone's growing environment, knowledge, experience, etc. There are great differences, and it is inevitable that positions and concepts are different. Therefore, we should reflect three times a day, be good at learning from each other's strong points and tolerate different opinions and practices (even wrong behaviors and viewpoints). If you only see each other's shortcomings and think you are superior, then the final result is likely to be a loner.
Getting along with others is an art, which requires us to study all our lives.
I hope I can help you.
