I have two characters in my name, and three characters in my son’s name. How many characters should I use to name my grandson?

The number of characters in the name is not important.

If you pay attention to the culture of names, please consider the five elements to fill in the gaps according to the birth date of Sun Tzu, whether to use two characters or three characters. The eight characters and five elements are very partial, so you can use three characters. If the five elements are complete, it is more convenient to use two characters.
