Perhaps you should try some spelling variations:
wong shiu » cong shu, song shin, wong sau
tong hui » wang hui
yan yang » yang yang, yao yang, dan yang
wong siu » kong siu, wong sau, wong siew
kang min » tang min, kang minah, kyung min
wan yan » wang yan, nan yan, wai yan
yang xi » yang di, yang yi, yang jui
kan min » han min, kian ming, kyaw min
xi lu » xu lu, li lu, xi bu

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

• Performing a fuzzy search may retrieve terms with similar spellings: wan yan yang xi lu ((kang min) or (kan min)) ((((wong shiu) OR (wong siu))) or (tong hui)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wan yan yang xi lu ((kang min) OR (kan min)) ((((wong shiu) OR (wong siu))) OR (tong hui)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan yan yang xi lu ((kang min) or (kan min)) ((((wong shiu) OR (wong siu))) or (tong hui)) ;*".
