11. Don’t be afraid of your enemies, they will at most kill you; don’t be afraid of your friends, they will at most betray you. But you must know that because there is a group of indifferent people, only with their silent acquiescence will there be killing and betrayal in this world.

12. "Treat others as others treat you." It means that the way others treat you is actually determined by the way you treat others. If you treat others coldly, how can others treat you warmly? If you want to be kind to others, you might as well express your own kindness to them first.

13. The attitude of others towards you is all designed by you and taught to others unconsciously by you. The most sincere friendship and the most incomprehensible hatred are gradually accumulated from this "reflection". The role of force is mutual, and people's attitudes are also mutual. What you give comes back to you.

14. Why do people not know what they look like even though there are mirrors in the world? If you want to know what you are like, look at how others treat you.

15. If you want others to smile at you, smile at others first; if you want to be hugged by others, hug others first; if you want to be friendly with others, be kind to others first; if you want to win the favor of others, To support, support others first; if you want to be praised by others, praise others first; if you want to be cared about by others, care about others first.
