Perhaps you should try some spelling variations:
yang yang » wang yang, wang yan
yan yang » yao yang, dan yang, tan yang
hua rene » hua ren, juan rene
yang jun » yang jui, pang jun, yang jin
wong sau » wong sam, wong shiu, wong lai
wong siu » wong shiu, kong siu, wong siew
wang » wing, wan, lang

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