Perhaps you should try some spelling variations:
juan rene » juan meng, juan rana
yan guan » gan guan, yang guang, yihan guan
yan yuan » fang yuan, nan yan, yan clan
yang jin » yang jie, yang jun, ying jin
yang jui » yang judy, yang di, yang xi
wong sau » wong sam, wong siu, wong shiu
yan tan » tan tan, yan clan, yan wang

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: wing ((((yan tan) OR (yan guan))) OR (yan yuan)) juan rene ((yang jin) OR (yang jui)) wong sau ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wing ((((yan tan) OR (yan guan))) or (yan yuan)) juan rene ((yang jin) or (yang jui)) wong sau ;~".
• Adding a wildcard symbol may retrieve word variants: wing ((((yan tan) OR (yan guan))) or (yan yuan)) juan rene ((yang jin) or (yang jui)) wong sau ;*.
