Perhaps you should try some spelling variations:
wang ying » wang yang, wang yong, wang jing
ying ying » ying yang, yirong ying, liang ying
hua irene » hua ren
ying hua » ming hua, wang hua, ying zhu
yang jun » pang jun, yang jin, yang judy
yang jui » yang judy, yang di, yang xi
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 ying ying hua irene (((shang OR zhang) jin) OR (((yang jun) OR (yang jui)))) wong sam ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ying ying hua irene (((shang OR zhang) jin) or (((yang jun) or (yang jui)))) wong sam ;~".
• Adding a wildcard symbol may retrieve word variants: wang ying ying hua irene (((shang OR zhang) jin) or (((yang jun) or (yang jui)))) wong sam ;*.
