Perhaps you should try some spelling variations:
lang yang » wang yang, yang yang, lang lang
wong shiu » wong siu, cong shu, song shin
wong sam » wong lai, kong sar, von sam
wong sau » wong siu, wong lai, kong sar
yang li » yang lin, yang di, yang yi
yang xi » yang di, yang yi, yang jui
ding ji » jing ji, ding qi, ying jin
l ding » lu ding, als ding

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 li) OR (yang xi)) l ding ji ((wong sam) OR (((wong sau) OR (wong shiu)))) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang yang ((yang li) OR (yang xi)) l ding ji ((wong sam) or (((wong sau) or (wong shiu)))) ;~".
• Adding a wildcard symbol may retrieve word variants: lang yang ((yang li) OR (yang xi)) l ding ji ((wong sam) or (((wong sau) or (wong shiu)))) ;*.
