Perhaps you should try some spelling variations:
tuan hua » tuan vu, yuan hui
yang jie » yang jin, yang di, yang jui
jie wong » jie song, kie wong, ji won
wong sau » wong sam, wong siu, wong shiu
wan yan » wang yan, nan yan, wai yan
yan hua » ya hua, wang hua, yan guan
tan hua » wang hua, tan chia, tan puay

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