Perhaps you should try some spelling variations:
wang yang » wang yan, wang liang, wang yanling
yang minh » sang minh, yang mind, kang minah
kong saur » kong sar, kong siu, kong your
yang y.c » yang yi, yang yao, yang 4.3
hua rent » hua ren
wong sau » wong sam, wong shiu, wong lai
wong siu » wong shiu, kong siu, wong siew

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 y.c hua rent yang minh ((((wong sau) OR (wong siu))) OR (kong saur)) ;~.
• Adding a wildcard symbol may retrieve word variants: wang yang y.c hua rent yang minh ((((wong sau) or (wong siu))) or (kong saur)) ;*.
