Perhaps you should try some spelling variations:
lang yang » wang yang, lang lang, ylang ylang
yang yang » wang yang, wang yan
yang jui » yang judy, yang di, yang xi
wong sau » wong sam, wong siu, wong shiu
lu ying » li ying, lu ding, lu xing
ku ying » ka ying, ku ring, hui ying
won sau » wong sam, wong siu

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

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