Which radical cannot be used to name the Year of the Horse?

There is a theory behind naming people according to their zodiac signs.

What should be avoided in naming names for people who belong to the Horse?

1. Avoid names containing "Zi Rat", "Wuma" and "Ugly Ox", which are the roots of the phenomena of conflict, punishment and harm. There are many obstacles and I feel weak.

2. Avoid words containing the radical or formal meaning of "water", which means that water and fire are incompatible, and there will be many disasters.

3. Avoid words with the meaning of "small", which may mean shrinking or downgrading.

4. Avoid containing the root word "meat", which means that money is hard to come by and hard work will lead to nothing.

5. Avoid words containing the word "small mouth", especially the root word "double mouth" or "double person". It means that the horse is too tired, and it also means that the horse is unruly.

6. Avoid words containing the root of "mountain" or "field". It means hard work. Unappreciated talent.

The eight-character naming is based on the five elements, happiness and taboos, and has nothing to do with the zodiac sign.
