Perhaps you should try some spelling variations:
lang wang » lang lang, hong wang, yan wang
ping wang » ping pong, hong wang
hua irene » hua ren
dong hua » wang hua, tong hui, dong hoi
yang kie » yang jie, yang di, yang yi
wong sau » wong sam, wong siu, wong shiu
yang xi » yang di, yang yi, yang jui

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: ((lang wang) OR (ping wang)) dong hua irene ((yang kie) OR (yang xi)) wong sau ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((lang wang) or (ping wang)) dong hua irene ((yang kie) OR (yang xi)) wong sau ;~".
• Adding a wildcard symbol may retrieve word variants: ((lang wang) or (ping wang)) dong hua irene ((yang kie) OR (yang xi)) wong sau ;*.
