"A chef who doesn't want to be a tailor is not a good driver." What does this sentence mean?

"A cook who doesn't want to be a tailor is not a good driver" has become a buzzword this year. When I first read it, I felt that the donkey's head was wrong and the horse's mouth was as stupid as "There are 10 cucumbers growing in Zhang San's field and 5 lettuces growing in Li Si's field. How many potatoes are there in ***?" But this confusing and confusing statement quickly became popular on the Internet and became a favorite joke. In addition to being humorous and hilarious, if you think about it carefully, it actually makes sense. . Today's society is really a strange society. I went to a science university and ended up pursuing a career in liberal arts. I studied music for many years, but my job had nothing to do with music. A top student in chemistry ended up pursuing a career in sales. Those who find their jobs unsatisfactory will then switch to other fields. It seems that this phenomenon is a waste of one's own youth and national resources. Not really. The diversity of modern society indeed requires diverse talents. From "one trick can be used all over the world" to "learn mathematics, physics and chemistry, you can travel all over the world without fear", to "all the people are soldiers" to learn English, learn computers, and learn cars. Parents can't wait to buy the "Encyclopedia" en masse and put it in their children's heads; teachers can't wait to cut the students' brains into eight pieces and use one piece as an eight-piece. At the annual talent recruitment fairs, recruiters in various fields no longer focus on a narrow field, but their vision becomes broader. They need not only professional talents, but also comprehensive talents. Therefore, applicants with CET-6 certificates, computer programmer certificates, and driving licenses have become popular at job fairs. It seems that the more certificates you have, the more talents you have. "A cook who doesn't want to be a tailor is not a good driver." Tailors, cooks, and drivers may seem to have nothing to do with each other, but they are actually related. Why can't a cook be a tailor? Tailors and chefs must also be good drivers. This is just like the teaching industry. If a teacher does not understand other fields, then he cannot apply them with ease, and cannot draw lessons from other sources, vivid images, and explain the profound things in simple terms, then he is definitely not a good teacher. Mr. Lu Xun said in "Usageism": "In short, we have to bring it. We have to use it, store it, or destroy it." At the beginning of the 20th century, Mr. Lu Xun realized that learning things from other countries and then considering what to use importance. Today, why can’t we say that “a cook who doesn’t want to be a tailor is not a good driver”? Then by extension, we can say: "Professionals who do not know other knowledge are not good managers." From this, we can say that "tailor", "cook" and "driver" themselves are related and inseparable. It requires that when we study professional knowledge seriously, we should not forget to study extensively and become young people with great wisdom and a big future in mind, who are in line with the spirit and trend of the times.
