Name the child Cheng Zimu. This name is neither pleasant nor unpleasant.
It is very good in a literal sense.
The word "self-muding" comes from Wei Zheng's "Ten Thoughts on Remonstrance to Taizong": "If you think about high dangers, you will be humble and self-mudging.". This name reflects your cultural quality. Thumbs up for you.
You don’t have to deal with some of the problems that are easily overlooked when naming.
Things to note when naming are:
Firstly, there are no uncommon words,
Secondly, there are no homophones that are easy to make fun of.
Third, it is not difficult to read.
You have done all three of the above.
So you can definitely call him out.
But one more thing:
The quality of your name has nothing to do with your zodiac sign.
