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 jun » pang jun, yang jin, yang judy
yang jui » yang judy, yang di, yang xi
wong sau » wong sam, wong siu, wong shiu
wang » wing, wan

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