Laozi's detailed deeds cannot be verified. It is said that Confucius came to Zhoudu from Shandong and asked him about "courtesy".
Laozi said, "The people who advocated your so-called ceremony are long dead, and even the bones are rotten, leaving only their words." When the gentleman arrives, he will drive out to be an official. If he is born at the wrong time, he should live in seclusion …
"I heard that rich people will give money to their friends, and virtuous people will give their friends proverbs. I'm not rich, so I'll give you a few words! Nowadays, some people who think they are smart have brought disasters to themselves, mainly because they like to ridicule others, praise others too much, think highly of themselves and be too proud. It is not good for a gentleman to let go of arrogance, desire and affectation. I can tell you so much. "
Confucius benefited a lot from this. After leaving Zhou Du and returning to Shandong, the disciple came forward and asked: What kind of person is Laozi? Confucius said to his disciples, "I know that birds can fly in the sky, fish can swim in the water and animals can run on the ground." If you can run, you can catch it with a net; Those who can swim can fish with hooks; Can fly, can shoot arrows. However, dragon, I don't know what to do. It can fly for nine days. The Laozi I visited today is like a dragon! "
This shows that Confucius' admiration for Laozi is beyond words.
