Why did Zheng Banqiao sing poems to drive away thieves? What happened?

Zheng Banqiao wrote poems to drive away thieves, saying that Zheng Banqiao had offended his superiors by opening a warehouse to help the people, so he resigned and went home. When he resigned from his post, he went home with "a bright moon on one shoulder and a cool breeze on the other", but he took a yellow dog and a pot of orchids with him. One night, the weather was very cold, the moon was dark and windy, and it rained heavily. Zheng Banqiao tossed and turned in bed and couldn't sleep. Just then, a thief visited the house. Zheng Banqiao thought, if you shout loudly, I'm afraid you can't cope with the thief fighting with yourself. But the thieves all entered the house. Pretending to be asleep, he was unwilling to let him do whatever he wanted in his own house and take whatever he wanted. So he thought for a moment, turned over, bowed his head and read a poem: "It's raining late at night, and the gentleman on the beam enters our door." By this time, the thief was close to the bed and was secretly surprised to hear the sound. Then I heard: "There are thousands of poems in my belly, but there is no gold or silver at my bedside." Now the thief thinks: that's it, don't steal. So the thief turned to go out and heard a voice inside saying, "Don't be surprised when you go out." The thief thought, since there is a bad dog, why doesn't he climb over the wall? I was about to climb the wall when I heard "Don't damage the orchid pot when crossing the wall." The thief looked carefully and saw that there was indeed a pot of orchids on the wall, so he carefully avoided it. As soon as my feet landed, I heard it say, "It's better to wear cold clothes and catch giants in the dark moon." We can see from Zheng Banqiao's Poem to Drive Thieves that, first of all, as an official, he was very honest and left with only a dog and a potted flower. People are also very generous. When they meet a thief, they remind him that there is a dog outside the house. Smart, resourceful, brilliant, export into poetry, this is the story of Zheng Banqiao's poetry to drive away thieves.
