yang jin » yang jun, shang jin, wang jing
ying jin » jing ji
wong sau » wong sam, wong siu, wong shiu

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

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