Who will explain to me the second, third and fourth changes of the occupation law mentioned in Zhu's "Yi Xue Enlightenment"?

If the six hexagrams are stable, they will be broken by this. When moving, break it with moving language. The slogan of two stubborn people, which is based on Yin, is stamped with "Yang dominates the past and Yin dominates the future". If both movable joints are male or female, take the upper joint and break it. Those who move three things are judged by the rude words among the three things they move. Four stubborn people, the quiet words below were broken. Five stubborn people break it with quiet words. If the six hexagrams are all moving, if they are two hexagrams of Gankun, it should be "broken". All other hexagrams except the two hexagrams of Gankun will be broken if the six hexagrams are moved. The above is Mr. Nan's breaking method, and the other is the breaking method mentioned in Zhu's Yi Xue Wu Dao: the six characters remain unchanged, so the characters are broken; A stubborn change, use this stubborn change to drop the word; There are two changes, which are broken by the two words of this hexagram, but the above is the main one; Three changes, changing with the original; This hexagram is chastity (body) and changed to regret (use); Four changes, two unchanged, but the following is the main; Five changes, unchanged mentality; Six ideas are changed, and the two ideas of Gan Kun are broken with the word "use".
