The meaning of Wang Wei is actually very good. It seems to be saying that the king is protecting. What is he protecting? If you want him/her to be smart, add: wisdom, wisdom, agility, understanding, etc. If you want him/her to be pretty, beautiful, add other meaningful words.
I thought of one myself, and added the word Wang Weiwei. I think the meaning is also very good. No matter he/she is beautiful, smart, healthy or anything else, he/she is the only one. It is also the only one protected by the king. Isn’t this a better implication?
