Please look at the name of Master Mumu.

The quality of any name depends on its role in Japan. If this name is a name that likes to use the five elements of god, it is basically certain that it is not bad. (But excluding the extremely weak eight characters, if the eight characters are too strong to avoid the gods, using the names of the weak gods will not work well, which is equivalent to throwing eggs at stones. ) But besides satisfying God's five elements, there is also a question of strength and good or bad mathematics. Basically, the three are the main ones, supplemented by other sounds and meanings.
