What does eight-character robbery mean?

The eight characters are actually the relationship between life and grams of the five elements. For example, the day you were born was fire, then your five elements are fire. The other seven words revolve around the day you were born. You were born as a fire, but the specific year of your birth is water. Water can kill fire, so water can kill you, which means you are an official. Similarly, you are fire, born in a month like Ding Bing, and like your five elements, they are all fire like brothers. If you are a fire, men and women like you are equal, and you are a fire, and the other party is Yin, it is called robbing money. It's just a different name
