Perhaps you should try some spelling variations:
irene yan » irene a, ren yan
hua irene » hua ren
yao yang » yang yang
wong sau » wong sam, wong siu, wong shiu
yan yan » yan yuan, nan yan, yang yang
yan jiu » yang jie, yang jin, pang jiu
wang » wing, wan, lang
sar » sara, star, saur

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: wang ((yan yan) or (yao yang)) hua irene yan jiu ((wong sau) OR (kong sar)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((yan yan) OR (yao yang)) hua irene yan jiu ((wong sau) OR (kong sar)) ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yan yan) or (yao yang)) hua irene yan jiu ((wong sau) OR (kong sar)) ;".
• Adding a wildcard symbol may retrieve word variants: wang ((yan yan) or (yao yang)) hua irene yan jiu ((wong sau) OR (kong sar)) ;*.
