Perhaps you should try some spelling variations:
yang hua » wang hua, yang hui, yang jui
ying hua » ming hua, wang hua, ying zhu
rene han » rene ten
wong siu » wong shiu, kong siu, wong siew
wong sau » wong sam, wong shiu, wong lai
wan yan » wang yan, nan yan, wai yan
han min » han men, kan min, chan ming

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 hua) or (ying hua)) rene han min ((wong siu) OR (wong sau)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wan yan ((yang hua) OR (ying hua)) rene han min ((wong siu) OR (wong sau)) ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan yan ((yang hua) or (ying hua)) rene han min ((wong siu) OR (wong sau)) ;".
• Adding a wildcard symbol may retrieve word variants: wan yan ((yang hua) or (ying hua)) rene han min ((wong siu) OR (wong sau)) ;*.
