Perhaps you should try some spelling variations:
yang john » young john, king john, yang jun
hua irene » hua ren
yan clan » das clan, yan guan, yan yuan
yang jin » yang jie, yang jun, ying jin
wong sau » wong sam, wong siu, wong shiu
yan tan » tan tan, yan guan, yan wang
wang » wing, wan, lang
sar » sara, star, saur

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