Perhaps you should try some spelling variations:
amin wong » amin hong, min hong
wong shiu » wong siu, cong shu, song shin
yan clan » das clan, yan guan, yan yuan
cheng lu » cheng chu, cheng _
yan fan » yang fan, yan guan, yan wang
chen yu » chen y, chen yulu
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 fan) OR (yan clan)) huang ((cheng lu) OR (chen yu)) amin wong shiu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yan fan) or (yan clan)) huang ((cheng lu) OR (chen yu)) amin wong shiu ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((yan fan) or (yan clan)) huang ((cheng lu) OR (chen yu)) amin wong shiu ;*.
