Perhaps you should try some spelling variations:
lang wang » lang lang, hong wang, ping wang
wang yong » wang yang, wang hyoung, wang yan
hua irene » hua ren
yong hua » dong hua, ying hua, wang hua
yang jin » yang jie, yang jun, ying jin
wong sau » wong siu, wong shiu, kong sar
wong sam » kong sar, von sam, wong max
lai » laid

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