How are the feng shui levels of The Deer and the Cauldron divided?

Owner, your Feng Shui level can be seen after you create it.

But if you live in a collective housing, then the house deed has nothing to do with Feng Shui.

What is really related to Feng Shui is the personal villa, the higher the better. As for the levels of Feng Shui, it seems that Feng Shui is not graded. What is graded is the house deed, and the grade of the house deed is divided into 1 to 4.
