Perhaps you should try some spelling variations:
yang yang » wang yang, wang yan
hua irene » hua ren
yan yang » yao yang, dan yang, tan yang
yang jin » yang jie, yang jun, ying jin
wong sau » wong sam, wong shiu, wong lai
wong siu » wong shiu, kong siu, wong siew
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: wan ((yan yang) or (yang yang)) hua irene yang jin ((((wong sau) OR (wong siu))) or (kong sar)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wan ((yan yang) OR (yang yang)) hua irene yang jin ((((wong sau) OR (wong siu))) OR (kong sar)) ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan ((yan yang) or (yang yang)) hua irene yang jin ((((wong sau) OR (wong siu))) or (kong sar)) ;".
• Adding a wildcard symbol may retrieve word variants: wan ((yan yang) or (yang yang)) hua irene yang jin ((((wong sau) OR (wong siu))) or (kong sar)) ;*.
