Perhaps you should try some spelling variations:
yang liang » wang liang, yan liang, yang yang
kang wong » kang young
wong shiu » wong siu, cong shu, song shin
cong sun » cong shu, cong van, wing sun
gan guan » yan guan, quan guan, fan guon
tang min » chang min, sang minh, yang mind
min kang » jin kang, man kann, min hong
dong di » dong sin

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: ((cong sun) OR (dong di)) ((yang liang) OR (gan guan)) tang min kang wong shiu ;~.
• Adding a wildcard symbol may retrieve word variants: ((cong sun) or (dong di)) ((yang liang) or (gan guan)) tang min kang wong shiu ;*.
