It is an old saying of China that a book cannot be judged by its appearance, but the sea cannot be measured. So, who can't judge a book by its cover? This man's compound surname is Dan Tai, and his name is unknown, but he is not a military commander in the blur familiar to martial arts fans. His real Dan Tai predates the fictional Dan Tai 1900 years.
At the end of the Spring and Autumn Period, the people of Wucheng (now Wucheng, Shandong Province) in Lu were thirty-nine years later than Confucius, the Great Sage. He was born out of step and ugly. It is said that he "has a low forehead, a narrow mouth and a low nose, and there is nothing remarkable about him."
So when he went to worship Confucius as a teacher, although Confucius didn't refuse him in order to keep his famous declaration of "teaching without discrimination", he always ignored him and left others on the bench. Tan Taiming was quite disappointed with Confucius' attitude of judging people by their appearances, and decided to leave Confucius and start a long and arduous self-study course.
Confucius, who judged people by their appearances, didn't pay much attention to the dinosaur man's killing on the platform, but his proud disciple Zi You (Yan Yan) appreciated the killing on the platform. When Ziyou returned to Qufu from Zairen in Wucheng to visit Confucius, Confucius asked him, "Did you get any talents there?"
Ziyou took the opportunity to praise Tantai's high spirits and bright days: "With Tantai's death, you can't go anywhere, it's not official business, and it's not too bad." In modern terms, it is "never take shortcuts when doing things, and never come to my house without business." But the stubborn Confucius was unmoved.
After self-study, Tan Tai found a new way to give lectures in Wu Chu.
Although Tan Taiming is ugly, he is broad-minded. He did not bear a grudge against Confucius because of his cold reception, but still took Confucius as his teacher and actively spread Confucianism.
He not only explained the Spring and Autumn Annals like Confucius, but also learned and taught self-cultivation, keeping the family in order, governing the country and leveling the world from the six arts. In his teaching, he advocates the attitude of "teaching people tirelessly", "teaching without being a crowd", the atmosphere of "learning without being tired" and "being ashamed to ask questions", "keeping pace with the times" and "reviewing the old and learning the new".
Tantai is famous for his profound knowledge and noble character, and he is deeply loved by the people in the south of the Yangtze River. More than 300 people have followed him. Over the past decades, he has trained a batch of good students with "all-round development of morality, intelligence, physique and beauty" for Jiangnan, and his reputation has also spread to various vassal States at that time.
When Confucius heard these news, he suddenly repented and was filled with emotion: he took people with tolerance and lost a hair (Tan Tai destroyed Yu Zi); Take people by their words, and get them back (meaning judge people by their appearances and misjudge their feathers; It is wrong to judge people by language.
