There are three gold characters in the five elements and eight characters.

It is very wrong to fill five lines without eight characters. Just fill in the five elements needed for the eight characters.

It is popular to use the method of "three talents and five grids" to name it now. In fact, this naming can be started by software, or by the method of "quick naming with three talents and five grids" in my Baidu space. "Three Talents and Five Styles" is easy to learn, and its name scores high, but it ignores more important factors than the five styles, such as five elements, meaning, rhythm, hexagrams and words, and so on, so although it scores high, it is not necessarily a good name.

I have an introduction to the traditional Book of Changes in Baidu Space. You can go and have a look if you are interested. I hope it will help you choose a name.
