Perhaps you should try some spelling variations:
lang yang » wang yang, lang lang, ylang ylang
yang yang » wang yang, wang yan
wong sam » wong sau, wong lai, kong sar
wong siu » wong shiu, kong siu, wong sau
yang yi » yang di, yang xi, yang jui
lu ding » lu xing, als ding
won sau » wong sau

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: lang yang yang yi ((li ying) OR (lu ding)) jin ((((won sau) OR (wong sam))) OR (wong siu)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang yang yang yi ((li ying) or (lu ding)) jin ((((won sau) OR (wong sam))) or (wong siu)) ;~".
• Adding a wildcard symbol may retrieve word variants: lang yang yang yi ((li ying) or (lu ding)) jin ((((won sau) OR (wong sam))) or (wong siu)) ;*.
