In the late Qin Dynasty, there was a man named Ji Bu who always kept his word and had a very high reputation. Many people had established a strong friendship with him. There was even a proverb circulating at that time: "It is better to get Jibu Yinuo than to get a hundred catties of gold." (This is the origin of the idiom "A promise of a thousand catties") Later, he offended Liu Bang, the emperor of the Han Dynasty, and was offered a reward for his arrest. As a result, his old friend not only was not deceived by the huge sum of money, but also risked the destruction of the nine tribes to protect him and save him from disaster. A person who is honest and trustworthy will naturally get a lot of help and can gain everyone's respect and friendship. On the other hand, if you are greedy for temporary comfort or small gains and break your trust with your friends, you will get "benefits" on the surface. But for this benefit, he ruined his reputation, and reputation is much more important than material things. Therefore, breaking trust with a friend is like losing a watermelon and picking up sesame seeds. The gain outweighs the loss.
