In the Ming Dynasty, Lü Kun wrote a book called "Groaning Language", which contains such a passage: Swallow without chewing during the meal break, leave without looking at the road, hand over people who do not choose to choose, say what they don't want to say, and do things if they don't want to

In the Ming Dynasty, Lü Kun wrote a book called "Groaning Language", which contains the following passage:

If you don't chew or swallow, if you don't look at the road break, you can leave without choosing, you can say what you don't want to say, and if you don't want to do it, you can do it.

This means that you must not swallow without chewing, do not go forward without looking at the road, do not make friends without choosing, do not say words without thinking, and do things without thinking.

This passage is a warning not to act hastily in everything in case of regret.
