lee chang » lee ching, lee chung, lee changgi
chang min » zhang ming, chang mae, chan ming
wong sau » wong sam, wong siu, wong shiu
hua lee » hwan lee, phua lye, zhuo lee

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