This sentence comes from Chapter 63 of Lao Tzu's Tao Te Ching: "Nothing, nothing, no taste. Good for evil, big or small. This number is easier and more difficult than it, because it is more detailed than it.
It is easy to do difficult things in the world, and it is necessary to do great things in the world. Therefore, a saint is not great after all, so he can become great. It is easy and difficult for a husband who promises lightly to break his promise. It is difficult to be a saint, so there is no difficulty in the end. "
It means: "Do what others should have done before they realize it, do what they should have done before the accident, and smell the smell before it comes out." We should regard small signs as major events and fewer signs as multiple consequences. Be kind to others' resentment.
To solve difficult problems, we should plan when it is easy to solve them, and to do big things, we should start small. All the difficulties in the world develop from the easy times, and all the major events in the world are formed step by step from small places. So saints never do great things directly, so they can achieve great things.
Promises made easily will certainly be difficult to keep, and if you think things too simply, you will certainly encounter too many difficulties. Therefore, it is more difficult for saints to see, so they will not encounter difficulties in the end. "
2, Taishan does not let the soil, so it can become big; Rivers and seas do not choose small streams, so they can be deep.

Content: Mount Tai can become great because it does not allow soil; Rivers and seas do not choose trickle, so they can be deep; The king is not only popular, so he can understand his virtue.
Therefore, Taishan does not give up any soil, so it can be so high; Rivers and seas do not exclude any trickle, so they can be so deep and wide; The emperor does not exclude any subjects, so he can show his kindness.
