What do you mean (the five elements are not lacking, and the eight characters like soil, so it's best to call them loanwords)? Please give me an example. What are the words?

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