No one is indispensable to anyone! The key to human relationships is sincerity!
Clothes torn can be mended, but broken glass is hard to heal!
The body gets sick, there's medicine to cure it, but wounded hearts have no cure!
People get along with each other, with just two words: sincerity!
To everyone, you should add more sincerity and less trickery, add more genuine feeling and less calculation.

Don't let money hurt your friends, and don't deceive others for profit.
The result of using unscrupulous methods is to ruin your character. The result of falsehood and deception is to lose people's trust.
Sincerity can be exchanged for genuine feelings, and genuine feelings can be cherished.
Don't abuse yourself because others care about you. Others can cherish you, and they can also ignore you.
You use what attitude towards people, people will respond with the same attitude.
Human relationships are always mutual. If I'm sincere to you, I'll be attentive to you.
If you deceive me with falsehoods, I'll treat you with indifference.
Warm hearts, warm hearts. Don't let people feel disheartened!
As long as you are sincere and genuine, you will surely gain true feelings.
