Perhaps you should try some spelling variations:
yang guang » yang yang, yan guan, yang liang
kang dong » kang young, jeng dong
wing ian » twinn ian, wing sun
wing tan » liang tan, hong tan, tin tan
tang min » chang min, sang minh, yang mind
min kang » jin kang, man kann, min hong
nan ya » nan yan, nana yaa
sin » sign, sind, skin

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: ((((wing ian) OR (wing tan))) OR (dong di)) ((yang guang) OR (nan ya)) tang min kang dong sin ;~.
• Adding a wildcard symbol may retrieve word variants: ((((wing ian) or (wing tan))) or (dong di)) ((yang guang) or (nan ya)) tang min kang dong sin ;*.
