Perhaps you should try some spelling variations:
yan xuan » yan yuan, wang xuan, yan clan
yan guan » gan guan, yan yuan, yang guang
vu irene » _ irene
yang jin » yang jie, yang jun, ying jin
wong sau » wong siu, wong shiu, kong sar
wong sam » kong sar, von sam, wong max
wang » wing, wan, lang

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