What are the maxims and reasons of Mencius' third chapter?

The motto and truth of Mencius in the third chapter are: if you love someone, don't kiss him; If you are kind to others, you will not be cured; Treat others with wisdom and you won't answer; If you don't respect them, you will look for yourself; If you are upright, you will return to this world. If you love others, but they are not close to you, you should reflect on whether your kindness is enough. If you manage people badly, you should reflect on whether your intelligence is enough. To treat others with courtesy, we must reflect on whether we have enough respect.

Excerpt from Mencius' Three Chapters

Mencius' three chapters are called born in sorrow, died in happiness, gained more help from the Tao, lost less help from the Tao, and fish is what I want. Mencius is a classic work of Confucianism, which was listed as four books by Zhu in the Southern Song Dynasty. The other three books are University, The Doctrine of the Mean and The Analects of Confucius.

Opportunities vouchsafed by Heaven are outmatched by terrestrial advantages, which in turn are outmatched by the harmony among people. The city of three miles, the country of seven miles, was invincible when attacked by the Lord of the Rings. If the husband attacks it, it will be the right time, and if it is invincible, it will be the right place. The city is not too high, the pond is not too deep, the army is not very profitable, and there is not much rice, so it is not as good as people and peace.

Therefore, the people in the territory do not take the border, the country does not take the risk of mountains and rivers, and the world does not take advantage of war. Those who gain the Tao help more, while those who lose the Tao help less. If you help less, your relatives will help, and if you help more, the world will be smooth. Take advantage of the world and attack your relatives. A gentleman wins without fighting.
