There should be a difference between "Yuan Henry Zhen" in the hexagrams of Zhouyi Gan and "Yuan Heng and Li Zhen" in the hexagrams. How to understand it?

At present, there are two views on Yuan Henry's understanding of chastity. The first one is Yuan, Heng, Li and Zhen, which are interpreted as "beginning, communication, smoothness and reality", in which Yuan is "beginning" in Gangua and "beginning" in other hexagrams. Another kind of understanding is "Yuan Heng and Li Zhen", which is interpreted as "great harmony is conducive to divination" or "complete access and smooth divination". These two statements are very authoritative. The so-called dry branch divination and Yuan Hengzhen's different understanding of divination are probably these two kinds. I hope to adopt.
