I don't know what the original change of the sixty-four hexagrams of Zhouyi is, but the teacher asked me to write it.

Favorable divination symbolizes harvest: it is conducive to going forward bravely, doing things, crossing the river and crossing the great stream. The elephant said: the wind and thunder are beneficial, and the gentleman will move when he sees it, and then change it if he has it. Revelation: When a gentleman sees good behavior, he should immediately follow it, correct his mistakes and constantly improve his good character.

Beneficial hexagrams are mutually stripped, wrong hexagrams are thunder, and comprehensive hexagrams are lost.
