How do you feel about the story of Zheng Ren buying shoes?

The fable of "Zheng people buy shoes" tells people the first truth: everything must have a standard.

A rule can be found in many of our fables. Most of the protagonists in fables are stupid, ridiculed and satirized, because their words or actions make jokes and are regarded as different or stupid by the world. For example, in the fable of "Zheng people buy shoes", the hero of the story wants to buy shoes. He forgot to take the measurements on his feet to the market, so he had to run home to take measurements. Then he went back to the market, and the market broke up. Finally, he stopped buying shoes.

People laughed at him for not trying it on with his own feet, but insisted on getting a good size. But this Zheng Man also has something worthy of recognition, that is, he knows that there must be a standard for doing things. If he wants to buy shoes, he must measure the size and buy shoes according to the size. This size is the standard for buying shoes. This is where he deserves to be recognized. For example, there should be a specific reference standard for interior decoration. Without standards, there will be all kinds of problems.

On the fable of Zheng people buying shoes

Once upon a time, there was a Zheng man who wanted to buy a new pair of shoes. He measured his feet in advance and put the measured size on the seat. When I arrived at the market, I forgot to bring my size. I picked out my shoes and found, "I forgot my size." Just go home and get the measurements. When he returned to the market, the market had already dispersed, and he didn't buy shoes at last. Someone asked, "Why don't you try on your shoes with your own feet?" He replied, "I would rather trust the measured size than my own feet."

This Zheng Guomin only believes in the size of his feet, not his own. Not only did he make a big joke, but he didn't even buy shoes and became a laughing stock. This fable is usually used to satirize those dogmatists who "only start from books, not from reality", because they think that "only what is in books is truth, and what is not written is not truth".
