Interpretation of Zhouyi divination …

The four pillars are birthdates's "three lives are interlinked" and "round Haiziping"

Plum blossom and Liu Yao are Zhouyi.

Qimen (Taoism) is more advanced. You have learned both of the above, but you may not get into the door of "fishing father"

But if you don't have a master, I'm afraid you'll never get in.
