Perhaps you should try some spelling variations:
yan yuan » yan guan, fang yuan, nan yan
vu irene » _ irene
yang jin » yang jie, yang jun, ying jin
wong sam » wong lai, kong sar, von sam
wong sau » wong siu, wong shiu, wong lai
song min » song ming, gong min, jong min
wai yan » wang yan, wei yang
yuan vu » tuan vu, yuan hui

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: wai yan yuan vu irene yang jin ((((wong sam) OR (wong sau))) OR (song min)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wai yan yuan vu irene yang jin ((((wong sam) OR (wong sau))) or (song min)) ;~".
• Adding a wildcard symbol may retrieve word variants: wai yan yuan vu irene yang jin ((((wong sam) OR (wong sau))) or (song min)) ;*.
