Perhaps you should try some spelling variations:
yang john » young john, king john, yang jin
john wong » john song, john bonn
hua rene » hua ren, juan rene
wong sau » wong sam, wong siu, wong shiu
yan tan » yan clan, yan guan, yan wang
tan tan » tas tan, tin tan, tang tang
wang » wing, wan, lang

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yan tan) OR (tan tan)) hua rene yang john wong sau ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((yan tan) OR (tan tan)) hua rene yang john wong sau ;*.
