Teaching without accepting is enlightening. Teaching without accepting the original sentence is: teaching without accepting, although it is useless, is like throwing stones without accepting. Today's husband Ishida, although moist and fertile, works well and is not satisfied. From the Song Dynasty, Zhang Zai's "Confucian Classics Cave and Learning the Great Plains" is a famous sentence inspired and induced.

It means: educating students, students are unwilling to accept it, even if it is forced to instill, it is useless, just like throwing water on a stone, of course, the stone will not absorb water. Now the land as hard as stone will dry up immediately even if it is irrigated with a lot of water, because it is not easy to absorb water.

Appreciation of Confucian Classics Grottoes

In Li Dong, the author put forward two political propositions: "merging fields" and "anti-feudalism". In his view, the "Zhou Li"-style "well field system" was implemented to solve the problem of inequality between the rich and the poor at that time. The specific method is to nationalize the land and then distribute it to farmers. "The land in the world should be laid out first, so that people can get one side", and the methods of "planting" and "renting" have been cancelled.

Regarding "feudalism", he said: "It is certain that soldiers in minefields belong to feudalism", and the author saw the disadvantages of excessive centralization. Especially when the border defense was weak. He believes that everything is under the control of the central court, and many things are not well managed. Therefore, it is necessary to implement "feudalism".

The "minefield" mentioned by Zhang Zai is subjectively to solve the uneven land; "Feudalism" subjectively aims at adjusting the authority of the central and local governments. Under the feudal system, it will never be realized, but it is just some fantasy schemes. However, these utopian plans are of great positive and progressive significance.
