A businessman in Jiyang sank while crossing the river. He grabbed a hemp pole and shouted for help. A fisherman heard the sound. The businessman quickly shouted: "I am the richest man in Jiyang. If you can save me, I will give you 100 two gold. " . After being rescued ashore, the businessman turned his face and refused to admit it. He only gave the fisherman 10 two gold. The fisherman accused him of breaking his word and going back on his word. The rich man said, "You are a fisherman. I can't make much money in my life. Is it not enough to suddenly get twelve taels of gold? " My husband must be very unhappy. Unexpectedly, the rich man capsized in the same place again. Someone tried to save him, and the person he cheated said, "He is a man of his word!" " "So the merchant drowned. It is accidental that the businessman capsized twice and met the same husband, but it is expected that the businessman will not be rewarded. Because if a person does not keep his word, he will lose the trust of others. So, once he is in trouble, no one wants to rescue him. Those who break their promises to others, once in trouble, have to sit still.
