The king's pearl

One day, a black stain was found on the king's precious pearl, no matter what the courtiers did, they could not remove the stain. Everywhere the minister went, no one could find the cause. 

 A poor man said, I know why the pearl turned black

 So the poor man was taken to the king and he told the king that there is a worm in your precious pearl that is eating from it. 

 The king laughed at him and said 

 O man, can a worm live in a pearl, but the poor man said, O king, I am sure there is a worm in it 

 The king said, "If not, I will beat your neck" and the poor man agreed.

 When they split the pearl, they saw that there is a worm under the black part 

 The king liked the wisdom of the poor man and ordered him to be placed in a corner of the kitchen and some of the leftovers were also given to him. 

 The next day, the king rode on a horse and turned to the poor man and said, “This is my best horse. What do you think?”

 The poor man said that he is the best at running fast, but there is also a problem. The king said what is the problem 

 The poor man said that at the height of his running, if he saw the river, he would jump into the river. The king did not believe him, and to test the horse and the validity of the poor man's claim, he rode by a river. 

 that the horse quickly threw himself into the water 

 The king was surprised by the wisdom of the poor man, and one night he left him in the previous place with leftover food and asked to bring him the next day.

 When he came to the king, the king asked him, O man, what else do you know? 

 I know that you are not a prince, the king got angry and threw him in prison, but because he had answered the previous two correctly.

 He made the king to find out the truth, and the king went to his mother and said, mother, tell the truth, who am I? It is true that I am not a prince. 

 After a little evasion, his mother said, "It's true, my son, because the king and I were unable to have children and we were afraid of the king's nephews taking the throne. When one of the servants of the court gave birth to you, we took you from him and said that we had a child."  And in this way, the secret of the prince not being the king was revealed 

 _The king asked the poor man again, but this time it was for how to find out about these events, and he said to the poor man, how did you know that I am not a prince, a horse, or a pearl? 

 The poor man said, I understood the pearl, since nothing is destroyed until it is destroyed from within 

 _And the horse, because its legs were woolly and had hoofs, I understood that during the Korean era, when horses and buffaloes used to graze in the same place, it had been caught by a buffalo and drank from the buffalo's milk, and that's why it likes water. 

 is coming 

 Then the king said, how did you know my authenticity?

 said the poor man 

 I had told you about the horse and pearls that were important to you, but you put me in a corner of the kitchen for two nights and did not reward me, and this was far from the dignity of a prince, and I realized that you are not a prince...!!
