It means that the mind can't be used indiscriminately, and tricks can't be used indiscriminately. It describes that people can't play with the essence of things according to their own consistent thinking when dealing with things.

A long-lasting folk story:

Once upon a time, there was a Wang Damao in Wangjiazhuang. People are lazy and lazy, but they are smart and have a lot of tricks.

One morning, his wife Liu took out a piece of cloth she knitted and asked Wang Damao to take it to the market to sell it in exchange for some oil, salt and money. Wang Damao agreed.

Wang Damao came to the market with a piece of cloth on his back. Nobody asked for it for an hour or two, so he sat down and fell asleep. When I woke up, I opened my eyes. No, the cloth was stolen.

around eleven o'clock, Wang Damao was weak and went home. When he got home, he saw his father-in-law going to his home, and a good idea came to him. He evaded his father-in-law, made a detour to the back of the house, quietly hid in the haystack in the Woods in front of the house, and stared at the house with bright eyes.

I saw his wife, Liu, smiling at his father's arrival. She pulled out a chair from the main room, made him sit at the gate, made tea and screened a glass of wine. Then she caught the black hen who laid eggs at home and killed her at the edge of the threshing floor, and went in to cook. My father-in-law had lunch and went back around 1: 3. His wife Liu sent his father to the intersection.

When his wife Liu turned home, Wang Damao climbed out of the haystack, patted the dust and swaggered home.

when Liu saw her husband coming back, he asked if the cloth had been sold. how much was it sold for？ Give her the money.

Wang Damao mysteriously told his wife that the cloth was sold for five yuan, which was used as tuition by his master.

Liu didn't believe it and asked him what he had learned. Wang Damao said the algorithm of learning. And solemnly said that your father came at eleven o'clock today, didn't you? You first moved a chair and sat him at the gate, then made tea, then sifted the wine, and then you killed the black bitch at home. Your father left around 1: 3, and you personally delivered it to the door. Honey, am I right?

Liu was surprised. Although he was a little dubious, it was true, so he didn't say much. Half a year has passed in an instant. The eighth day of September is my father-in-law's 6th birthday. My father-in-law's family is a moderately wealthy family in the local area. On weekdays, I don't think much of Wang Damao, who is lazy. My two uncles and sisters also look down on Wang Damao. Wang Damao decided to take this birthday to take a breath.

On the evening of the seventh day, Wang Damao hurried to his father-in-law's house under the pretext of going out for a walk, and secretly took the big ox tied to his father-in-law's house and hung it in a ravine not far behind his house. There is a chaotic grave, and no one passes by during the day, let alone at night.

In the early morning of August 1st, Liu called Wang Damao to pay his birthday respects. Wang Damao asked his wife to go first and dig a piece of land to go later. Liu couldn't get over it, so she went back to her parents' home first, because she was going to help.

When Liu arrived at his father's house, he helped to do things. After ten o'clock, many guests came to celebrate their birthdays, and some old people went to the pigsty to see the pigs and the cowshed to see the cows. When I found that the cowshed was empty, I quickly told Liu's father.

Hearing this, Liu Fu was shocked. At that time, a cow was more valuable than a car now. Liu's father was in a rash. After listening to this, Liu suddenly remembered that her husband Wang Damao could calculate and told his father. With a wave of his hand, Liu Fu said, Then hurry back and ask Wang Damao to come over.

Liu ran three steps at a time, went home, told Wang Damao about it, and urged him to follow her quickly. Wang Damao changed his clothes with great difficulty and followed his wife to the Yue family.

My father-in-law greeted him personally for the first time, pretending to smoke and ordering someone to deliver tea, and gently begged him to make a quick calculation. Wang Damao pretends to say yes, sits in a chair and smokes. My father-in-law poured another glass of wine. Wang Damao took a sip, mumbling, and his left finger flexed and stretched.

after a while, I suddenly shouted: Yes, someone. Then Huo Ran stood up and proudly told his father-in-law that your cow was taken away by a thief last night. When passing through the chaotic grave, the thief wanted to defecate, so he hung the cow from a big fir tree and squatted aside to defecate. Suddenly a white shadow flashed, scaring the thief to lift his pants and run away. Where the cow is still hanging now. Send someone to get it back quickly.

Father-in-law quickly ordered the other two sons-in-law to lead the cattle. Two son-in-law came to the chaotic grave with a grain of salt and courage, and really saw the big ox tied to the fir tree. Two people also carefully looked at the side, sure enough, there are a bunch of people's shit. I can't help but sit up and take notice of my uncle Wang Damao, saying that this guy has really become a god.

The two uncles took their family back to their father-in-law's, and the father-in-law was overjoyed, and all the guests stared at Wang Damao with their thumbs up and praised him. At lunch, Wang Damao was invited by his father-in-law to sit on the table, and everyone brought cups to propose a toast. Wang Damao was so proud that he enjoyed the taste of holding the moon with all the stars for the first time and became a master.

From then on, Wang Maohui's psychic skills were spread in four miles and eight townships.

this matter reached the local county government. Zhang Chengli, a county official, didn't quite believe it and decided to set up a method to test Wang Damao. One night, Zhang Chengli personally packed the gold, silver and jewels from corruption in a suitcase, sealed it and packed it. He carried it alone to the well behind the boudoir where his only daughter lived, and hooked the suitcase into the bottom of the well with a rope tied with a hook at one end.

Zhang Chengli never knew that his actions were clearly seen by his only daughter standing at the back window enjoying the scenery.

The next morning, Zhang Chengli, the county magistrate, called two courtiers, saying that thieves came to his house last night and stole some money and things, and sent two men to fetch Wang Damao as soon as possible to do the math.

The two courtiers got orders and hurried to Wang Damao's house to explain their purpose. Hearing this, Wang Damao was scared and shouted in his heart. But you can't reveal it, and you can't refuse it. Had to nod, with two chief on the road.

here we are. The county magistrate greeted him. Along the way, Wang Damao had thought it over, but it was a disaster to avoid, and it was not a disaster to avoid. I simply wanted to be a full fool and eat and drink for a few days first. So he pretended to have answers and said to the county magistrate, you have a lot of property and everything is very small. It will take a week to calculate it all. You have to find me a quiet house, eat and drink well every day, and don't disturb me.

naturally, the county magistrate agreed, so he found a house next to his daughter's house and let Wang Damao live in it.

after Wang damao moved in, he ate and drank the sea every day, but he couldn't taste any delicious food, and his heart became afraid every day. On the sixth day, after supper, Wang Damao slept for two hours and woke up. He remembered that if he couldn't figure it out tomorrow, he would definitely be punished by the county magistrate, beaten raw, charged with cheating the world and stealing fame, and put into prison, and he couldn't help crying.

so he was determined to kill himself. He dragged his feet out of the door, looking for a place to commit suicide in a nearby courtyard, and suddenly found the well behind the house. He felt that the well was good, so he looked down at the edge of the well. After watching it for a while, I was worried that the well was not deep enough and it would be uncomfortable to flood, so I stood up and found a bamboo stick nearby and inserted it into the well to fiddle with it.

All this happened to be discovered by the only daughter of the county magistrate. In order to discover her father's secret, she quietly rushed over and said to Wang Damao, don't mess around here, my father lost a box of things in it a few days ago. I don't think you are a bad person, so I didn't shout. You should go. Please don't let my father catch you. He is not easy to mess with.

Wang Damao was overjoyed and almost jumped with excitement. Pretending to be calm, he told the county magistrate's daughter that he was the psychic hired by his father to find the lost property. Just now, he had calculated that the property was in the well, so he came to look at the search, only to disturb the big lady. Please forgive me.

the daughter of the county magistrate gave a cry and turned back to her room. Wang Damao followed him back to his room, poured a large glass of wine, pulled a chicken leg, drank heavily, and ate large pieces of meat, feeling so delicious. I am also whispering in my heart: God helps me. After eating and drinking enough, I fell into bed, fell asleep and fell asleep.

The next morning, Wang Damao was awakened by the chief and brought to the county magistrate. The county magistrate smiled somberly and asked if he had worked it out. Wang Damao proudly told the county magistrate that even if it came out last night, your property was not stolen by thieves, but you yourself sank into the well.

The county magistrate was dumbfounded and admired. In accordance with the agreement, Wang Damao was paid a hundred and twenty pieces of silver and named as a divine operator. And leave Wang Damao as a tout in the official's son.

Wang Damao asked for a silver reward and refused to be an official. The master only allowed him to cast his magic twice, but it didn't work the third time. That is to say, the word is no more than three. The county magistrate agreed to his request when he saw that he was determined to go and had no value for reuse.

At once, Wang Damao marched home with money. Since then, I have lived in love with my wife and lived a stable life. He always told himself that tricks should not be played for a long time, and he must be satisfied and can no longer be clever.
