Perhaps you should try some spelling variations:
hua irene » hua ren
yang hong » wang hong, yang hongli, quang hong
yan ming » yuan ming, wan ming, kian ming
ming hua » ying hua, ming hung, wang hua
pong sar » kong sar, pong part, wong sau
wong sam » wong sau, wong lai, kong sar
wang » wing, wan

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