Perhaps you should try some spelling variations:
wang liang » wang yang
hua irene » hua ren
irene yan » irene a, ren yan
wong sau » wong siu, wong shiu, wong lai
wong sam » wong lai, kong sar, von sam
yan hua » tan hua, ya hua, wang hua
yan jiu » yang jie, yang jin, pang jiu

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) or (wang liang)) yan hua irene yan jiu ((wong sau) OR (wong sam)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang yan) OR (wang liang)) yan hua irene yan jiu ((wong sau) OR (wong sam)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yan) or (wang liang)) yan hua irene yan jiu ((wong sau) OR (wong sam)) ;*".
