From "On Pan Geng in Shangshu": If you look at the fire, you will also make a clumsy plan, which is to escape. If the net is in the outline, it is organized but not dull. If the farm serves the field, the manuscript has autumn, and later generations will derive idioms from this allusion. Idioms tell people to observe carefully before doing things, see the essence through appearances, and know things like the back of their hands. Only by recognizing the problem clearly can we get twice the result with half the effort.
Just like knowing everything, both of them have the meaning of knowing things clearly. The difference is that to see the fire from the outside of the cave, it is important to observe it thoroughly. If you know it like the back of your hand, it is important to understand it clearly. If you look at fire, it refers to the observation of things, but it cannot be used to understand people, so the scope of application is small. Knowing everything refers to knowing people or things, which has a wide range of applications.
The background of the story.
Pan Geng is the tenth grandson of Shang Tang. In order to avoid floods and revive the Shang Dynasty, he led his subjects to move to Yin (now Anyang, Henan). This move was opposed by all parties, and Pan Geng told his subjects three times. "On Pan Geng in Shangshu" records: Pan Geng said: I want to warn you and teach you a lesson in order to get rid of your selfishness, so that you should not be arrogant and pursue comfort.
I know this as well as watching fire. If I'm not good at planning, it's a mistake. Just as only by tying the net to the outline will it be organized and not disorderly. Just as farmers can have a good harvest in autumn only if they work hard. You can get rid of selfishness and give tangible benefits to your subjects, even your relatives and friends, then you dare to say that you have accumulated kindness.
