yuan hui » jaan hui, tuan hua, yang hui
wong sau » wong siu, wong lai, kong sar
wong sam » wong lai, kong sar, von sam
yan jiu » yang jie, yang jin, pang jiu
wang » wing, wan, lang
ren » rent, rene, rein

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

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