Perhaps you should try some spelling variations:
lang yan » wang yan, wang yang, zhang yan
wong sau » wong siu, wong shiu, wong lai
wong sam » wong lai, von sam, wong max
yan yan » yan yuan, nan yan, yang yang
yan hua » tan hua, ya hua, wang hua
hua see » chua tee, chua yee
yan jiu » yang jie, yang jin, pang jiu
sar » sara, star, saur

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

• Performing a fuzzy search may retrieve terms with similar spellings: lang yan yan hua see yan jiu ((((wong sau) OR (wong sam))) or (kong sar)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: lang yan yan hua see yan jiu ((((wong sau) OR (wong sam))) OR (kong sar)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang yan yan hua see yan jiu ((((wong sau) OR (wong sam))) or (kong sar)) ;*".
