Perhaps you should try some spelling variations:
chang won » chang soon, chang ann, chang min
chan ming » kian ming, chan eng, chan fong
wang nan » wang yan, wang ban, wang dan
yang jin » yang jie, ying jin, shang jin
yang jun » yang jui, pang jun, yang judy
hong hai » shang hai, zhong tai, dang hai
hua ren » hua chen
nan ya » nan yan, nana yaa

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: wang nan ya hua ren ((((chang won) OR (chan ming))) OR (((yang jin) OR (yang jun)))) hong hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang nan ya hua ren ((((chang won) or (chan ming))) or (((yang jin) OR (yang jun)))) hong hai ;~".
• Adding a wildcard symbol may retrieve word variants: wang nan ya hua ren ((((chang won) or (chan ming))) or (((yang jin) OR (yang jun)))) hong hai ;*.
