Perhaps you should try some spelling variations:
yang vinh » yang jin, sang minh, yang jing
wang yang » wang yan, wang liang, wang yanling
hua rene » juan rene
yang lin » yang jin, wang lin, yang li
long shu » cong shu, tong shui, long du
wong sam » wong sau, wong lai, kong sar
yang yi » yang di, yang xi, yang jui
hua ren » hua chen

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 yang yi ((hua rene) OR (hua ren)) ((yang vinh) OR (yang lin)) ((long shu) OR (wong sam)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yang yi ((hua rene) OR (hua ren)) ((yang vinh) or (yang lin)) ((long shu) or (wong sam)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yang yi ((hua rene) OR (hua ren)) ((yang vinh) or (yang lin)) ((long shu) or (wong sam)) ;*.
