Perhaps you should try some spelling variations:
john wong » john song, john bonn
dang anh » duong anh
dan yang » daun yang, tan yang, wang yang
ren yang » ren yan, chen yang, pei yang
wong sar » kong sar, wong sam, wong sau
tuan hua » yuan hui
tuan vu » thanh vu
tan hua » wang hua, tan chia, tan puay

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

• Performing a fuzzy search may retrieve terms with similar spellings: dang anh ((((tuan hua) OR (tuan vu))) or (tan hua)) ((ren yang) or (dan yang)) john wong sar ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: dang anh ((((tuan hua) OR (tuan vu))) OR (tan hua)) ((ren yang) OR (dan yang)) john wong sar ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "dang anh ((((tuan hua) OR (tuan vu))) or (tan hua)) ((ren yang) or (dan yang)) john wong sar ;*".
