Seeing this sentence, I suddenly thought of a classical Chinese article I did in junior high school. The protagonist of this article is Liu Rong. Liu Rong is studying in a room. There is a low-lying place in this room, but Liu Rong doesn't care. One day, his father found out about it, so he educated Liu Rong and said, "If one room is not cured, how can it be for the country and the world?"
Yes, managing a room is really a piece of cake compared with managing state affairs. This is our natural idea. However, this kind of understanding separates the universal connection between things, which is not in line with philosophical truth, and it is possible to make mistakes when looking at things with this kind of understanding.
Imagine that it takes ability and experience to do great things, but where do these experiences come from? I think this kind of ability and experience still comes from small things.
For example, if you know the tools for making tables, you can make tables. Understanding tools is a piece of cake, but making a watch requires a certain technical content. If we regard cognitive tools as trivial things and watch as important things here, we can easily find that they are actually trivial things. Because you don't even know the tools, how to use them, and how to build a table? And if you have to bite the bullet and do it, it may ruin the good wood!
So logically, what Liu Rong's father said is very reasonable. Because there is a good way to govern the country in the method of governing the house, and you can't even find the method of governing the house, how can you find a country that is more difficult than governing the house?
Therefore, we should not underestimate any small matter, because the truth contained in small things often benefits us a lot.
