Words warning people not to judge a book by its cover.

You can't judge a book by its cover. Just as water cannot be used in water.

You can't judge a person's talent, quality and behavior just by his appearance. Feng Ming's magnum "Awakening the world always says, selling oil lang monopolizes the flower head": "All that glitters is not gold, and the sea can't be measured." In physiognomy, we should not only look at appearance, but also examine moral conduct, that is, care for each other. "Pure Yang Law" says: "Those who are not proud (ugly) are hard to tolerate." Its note: "Monk Hu said: Don't be disrespectful, white jade is hidden in the middle." If you can really know that there is evil in beauty and beauty in evil, then you won't lose in physiognomy. "In other words, a good fortune teller is not judge by appearances, but is good at finding the best in the garden." Guiguzi distinguishes the micro-awn "also said:" On the shape, you can see the leopard in the tube. "People who don't leave the form, don't stick to the rules, can't see or hear, and look good are also good." "Han Feizi Xianxue" said: "A surname is a gentleman's appearance, and Zhong Ni took it from him several times. After being with him for a long time, he stopped calling him that. ..... So Confucius said:' Take a person by the amount, and lose his feathers! "'Confucius's mistake in looking at people' is often quoted by later generations as an example that we must be moral at the same time.
