Once upon a time, there was a man in the state of Zheng. He wanted to buy a new pair of shoes. So he measured the size of his feet early, wrote it on a small piece of paper, and then carefully placed it beside his seat.
On the day of the market, he came to the shoe store cheerfully. The shoe store was full of all kinds of shoes, a dazzling array. Among the many shoes, he took a fancy to a very beautiful pair of shoes and was very attracted. At this time, he suddenly remembered that he had forgotten to bring the piece of paper with the size written on it when he went out.
So, without hesitation, he turned around and was about to go home to get the piece of paper. The owner of the shoe store was very puzzled and asked him, "Why don't you directly try on the shoes with your own feet? In this way, you will know if they fit."
This man from Zheng answered seriously, "I would rather trust the measured size than my own feet." After saying that, he hurried home to get the piece of paper.
By the time he returned to the market, panting, with the piece of paper, the market was almost over. He quickly ran to the shoe store, took out the piece of paper and tried on the shoes according to the size. But at this time, he found that because he hadn't tried on the shoes in time before, the shoes of the right size had been bought by others. In the end, he could only go home dejectedly without buying any shoes. This story tells us that in life, we should not be as rigid as this man from Zheng, but should know how to be flexible.
