Perhaps you should try some spelling variations:
juan meng » juan rene, jui meng, yuan ming
yan guan » gan guan, yan yuan, yang guang
ying jin » yang jin, jing ji, yang jie
yang jui » yang judy, yang xi, yang yi
wong sau » wong sam, wong siu, wong shiu
yan san » yan clan, yan wang, yan yuan
wang » wing, wan, lang

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