What do you mean (the five elements are not lacking, and the eight characters like soil, so it is best to name them earth-borrowing words)? Please give me an example. What are the words?

eight characters like soil, that is, when naming a name, it is best to bring the five elements of soil. For example: Cheng surname, the five elements belong to fire, and the second word is best to use the words Yong, Yi, Kui and so on. In this way, and Cheng surname just five elements. If not, consider using it in the position of the third word. I hope it helps you.
