Perhaps you should try some spelling variations:
dinh tuan » binh thuan, dinh tung, binh tran
yang john » young john, king john, yang jin
john wong » john song, john bonn
anh tuan » anh tran, oanh tran
ren yang » ren yan, chen yang, dan yang
wong sau » wong sam, wong siu, wong shiu
hua ren » hua chen
wang » wing, 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 OR wan) ((anh tuan) OR (dinh tuan)) hua ren yang john wong sau ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang or wan) ((anh tuan) OR (dinh tuan)) hua ren yang john wong sau ;~".
• Adding a wildcard symbol may retrieve word variants: (wang or wan) ((anh tuan) OR (dinh tuan)) hua ren yang john wong sau ;*.
