Perhaps you should try some spelling variations:
hua irene » hua ren
wang yin » wang yan, wang qin, wang yidan
wang lin » wang li, wang qin, yang lin
yang hua » wang hua, yang hui, ying hua
ying jin » yang jin, jing ji, yang jie
yang jun » yang jui, pang jun, yang jin
wong sam » wong sau, wong lai, kong sar

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