【Idiom Story】:

Legend has it that the god who manages horses in the sky is called Bole. In the human world, people refer to people who are good at distinguishing the good and bad of horses as Bole.

The first person to be called Bole, whose real name was Sun Yang, was a native of the Spring and Autumn Period. Because of his excellent study of horses, people forgot his original name and simply called him Bole, and he has remained until now.

Once, Bole was entrusted by the king of Chu to buy a horse that could travel thousands of miles a day. Bole explained to the king of Chu that thousands of horses are rare, and it is not easy to find them, and he needs to visit various places, so please do not need to be in a hurry, he will try his best to get things done.

Bole traveled to several countries, carefully searched for the Yanzhao area, which is rich in famous horses, and worked hard, but still did not find the good horse he liked. One day, Bole returned from the country of Qi, and on the way, he saw a horse pulling a salt cart, struggling to travel up a steep slope. Ma was tired and panting, and every step was very difficult. Bole has always been close to horses, and he couldn't help but walk up. When Ma saw Bole approaching, he suddenly raised his head and widened his eyes, and hissed loudly, as if he wanted to confide in Bole. Bole immediately judged from his voice that this was a rare steed.

Bole said to the driver, "This horse gallops on the field, and no horse can compare with it; But when used to pull a cart, it is inferior to an ordinary horse. You'd better sell it to me.

The driver thought that Bole was a big fool, and he thought that the horse was too ordinary, that he had no strength to pull the cart, that he had eaten too much, and that he was skinny, so he agreed without hesitation. Bole took away Maxima and went straight to the Chu State. Bole led the horse to the palace of the king of Chu, patted the horse's neck and said: I have found a good master for you. As if he understood what Bole meant, Maxima raised his front hooves to shake the ground to a gurgling sound, hissing his neck, and his voice was loud, like a big bell stone plate, straight up to the sky. The king of Chu heard the neighing of horses and walked out of the palace. Bole pointed to the horse and said, "King, I have brought you Maxima, please watch carefully."

When the king of Chu saw that the horse led by Bole was so thin that he couldn't look good, he thought that Bole had fooled him, and was a little unhappy, and said: I believe that you will look at the horse, so I let you buy a horse, but what kind of horse are you buying, this horse is very difficult to walk, can you go to the battlefield?

Bole said: This is indeed a thousand-mile horse, but it has been pulled for a while, and it is not fed carefully, so it looks thin. As long as you feed carefully, within half a month, you will definitely recover your strength.

When the king of Chu heard this, he was a little skeptical, so he ordered the horseman to do his best to feed the horse, and sure enough, the horse became a strong horse. The king of Chu crossed his horse and raised his whip, but he felt that the wind in his ears and the wheezing kung fu had run out of a hundred miles.

Later, Maxima made a lot of contributions to the king of Chu galloping on the battlefield. The king of Chu had more respect for Bole.
