Perhaps you should try some spelling variations:
wang yidan » wang yan
wang dan » wang yan, wang ban, wang yang
yang hua » wang hua, yang hui, ying hua
yang jin » yang jie, yang jun, ying jin
yang jui » yang judy, yang di, yang yi
wong sau » wong sam, wong siu, wong shiu
hua ren » hua chen
yang xi » yang di, yang yi

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((wang dan) OR (wang yidan)) yang hua ren ((((yang jin) or (yang xi))) or (yang jui)) wong sau ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang dan) OR (wang yidan)) yang hua ren ((((yang jin) OR (yang xi))) OR (yang jui)) wong sau ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang dan) OR (wang yidan)) yang hua ren ((((yang jin) or (yang xi))) or (yang jui)) wong sau ;*".
