Perhaps you should try some spelling variations:
wanna john » randa john
huang ying » huang jing, huang ting, huang yang
wang john » wong john, wrong john, king john
fang wei » wang wei, zhang wei, liang wei
wong sau » wong sam, wong shiu, wong lai
wong siu » wong shiu, kong siu, wong siew
fang xi » fang xia, yang xi, fang ri

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: huang ying ((fang xi) OR (fang wei)) x ((wang john) OR (wanna john)) ((wong sau) OR (wong siu)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "huang ying ((fang xi) or (fang wei)) x ((wang john) OR (wanna john)) ((wong sau) or (wong siu)) ;~".
• Adding a wildcard symbol may retrieve word variants: huang ying ((fang xi) or (fang wei)) x ((wang john) OR (wanna john)) ((wong sau) or (wong siu)) ;*.
