This story is also called "Warm Wind in Meng Ke County".

Meng Changjun, the prime minister of Qi, had a diner named Wen Feng. He was resourceful and eloquent, and was sent to Xue to collect debts. Wen Feng asked Meng Changjun what to buy after debt collection. The host replied, "You can buy whatever I lack."

When I arrived in Xue, I saw that all the debtors were poor households. I immediately announced that I would write off my debts and burn the debt contracts of poor households. After meeting Wen Feng, Meng Changjun asked him what he bought for himself. Wen Feng said, "You have everything. I only bought you benevolence." When he learned that Xue had been exempted from the debt for a long time in his name, he was angry and annoyed, but it was irreparable and helpless.

Later, the phase was abolished, so he had to retire and live Xue's life. When Xue learned of his arrival, he helped the old and brought the young, and walked dozens of miles to meet him. At this time, it dawned on him that he was grateful for the value of benevolence and righteousness he bought. Wen Feng said, "The sly rabbit has three caves, and only its dead ear can avoid it. There is a cave today, and I have to lie down without a high pillow. " It means that the three caves of the cunning rabbit are out of danger of death. You only have a place to live, you can't sit back and relax! This is the origin of the idioms "Three Caves of a Cunning Rabbit" and "Sit back and relax".
