I would like to ask "Lianshan, Guizang, Zhouyi, Sanyi Detailed, Dianmo and Gu Xun" in the three-character classics. What book is meant by "Olympic with oath"?

There are mountains, hiding, Zhouyi and three meanings.

[Revelation] Although the Book of Changes is a divination book of ancient people in China, it expounds extremely profound philosophical principles. Just like the ups and downs, the extremes of discussion must be reversed everywhere.

The translated works of Lianshan, Guizang and Zhouyi are three ancient books of China, which are collectively called "three changes", and "three changes" are books that explain the cyclic changes of the universe in the form of hexagrams.

There is a canon, a decree and an oath.

[Revelation] Classic books are very precious historical materials. From the content point of view, it is very similar to the government archives in our country now, which can let us know the history at that time and learn a lot of useful knowledge from it.

Classical translation is divided into six parts: first, the basic principles of founding a country; Second, the plan of governing the country; Three training, that is, the attitude of the minister; Four letters patent, that is, the announcement of the monarch; Five vows, stand up and announce; Six lives, the order of the monarch.

I, Duke Zhou, wrote the ruling system of six officials into a weekly ceremony.
