Perhaps you should try some spelling variations:
lang lang » ylang ylang
ping wang » ping pong, hong wang
hua irene » hua ren
dong hua » wang hua, tong hui, dong hoi
yang jie » yang jin, yang di, yang xi
yang jui » yang judy, yang di, yang xi
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: ((lang lang) OR (ping wang)) dong hua irene ((yang jie) OR (yang jui)) wong sau ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((lang lang) or (ping wang)) dong hua irene ((yang jie) OR (yang jui)) wong sau ;~".
• Adding a wildcard symbol may retrieve word variants: ((lang lang) or (ping wang)) dong hua irene ((yang jie) OR (yang jui)) wong sau ;*.
