The Meanings of His Name(s)

We've been asked what our new son's Chinese name means, and also asked why we chose Aaron.
First of all, his Chinese name of Bao Xinsheng...
For those of you who can read Chinese, the Chinese characters of his name are 宝 新 盛.
Bao = the surname, with no particular meaning, though it translates as "precious" or "treasured" All children in his orphanage have the same surname of Bao.
Xin = means "new" or "recent"
Sheng = means "flourishing", or "prosperous", or "energetic". It can also mean "popular" or "grand."
Combined, Xinsheng means "newly prosperous" or "newly popular". In either case, it conveys a meaning of blessing or well wishes that his life be fulfilled as a prosperous or popular person.

His new name, as our son...
Aaron (means "mountain of strength," Hebrew) - Needless to say, we find the meaning of the name extremely fitting for this little brave boy who has survived and persevered against the odds, in an orphanage in China...
Donald (after Nicole's father, Irish, meaning "great chief" and "mighty")
Gar (name given to all boys in Donovan and Aaron's generation in the Ho family)
Sing (Cantonese pronounciation of Chinese character which is Sheng in Mandarin, meaning "prosperous")
Walsh (Nicole's last name)
