Perhaps you should try some spelling variations:
yang guang » yang yang, yang liang
yan xuan » yan yuan, wang xuan, yan clan
yan guan » gan guan, yan yuan, yihan guan
vu irene » _ irene
yang jui » yang judy, yang di, yang xi
jui wong » ji won, jui meng
wong sau » wong sam, wong siu, wong shiu
wang » 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 OR wing) ((yan xuan) OR (((yan guan) OR (yang guang)))) vu irene yang jui wong sau ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang or wing) ((yan xuan) or (((yan guan) OR (yang guang)))) vu irene yang jui wong sau ;~".
• Adding a wildcard symbol may retrieve word variants: (wang or wing) ((yan xuan) or (((yan guan) OR (yang guang)))) vu irene yang jui wong sau ;*.
