yang hua » wang hua, yang hui, ying hua
wang hui » wang hua, wang zhi, wang wei
ying jin » yang jin, jing ji, yang jie
yong sau » wong sau, kong sar, wong sam
yan jim » yang jie, yang jin
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 dong ((yang hua) or (wang hui)) ren ((((yan jim) OR (yan jiu))) or (ying jin)) yong sau ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wang dong ((yang hua) OR (wang hui)) ren ((((yan jim) OR (yan jiu))) OR (ying jin)) yong sau ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang dong ((yang hua) or (wang hui)) ren ((((yan jim) OR (yan jiu))) or (ying jin)) yong sau ;".
• Adding a wildcard symbol may retrieve word variants: wang dong ((yang hua) or (wang hui)) ren ((((yan jim) OR (yan jiu))) or (ying jin)) yong sau ;*.
