What does it mean that the five elements are not lacking and the numerology is weak?

This is a term. It doesn't matter if you don't understand, because it has no practical significance.

The five elements are not lacking, that is to say, Jin Mu, fire, water and earth are all in your constellation. Weak body numerology refers to the rise and fall of a constellation, which is generally divided into strong body and weak body, mainly to take out the five elements of God. Not that you are weak, but a measure of the eight characters.
