Outline of the fable "Zheng people buy 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. Choose shoes.

Only to find out: "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".
