Perhaps you should try some spelling variations:
kong saur » kong sar, kong siu, kong your
yong sau » wong sau, kong sar, wong sam
pang jiu » pang jun, yang jie, yang jin
hua rent » hua ren
yan yan » yan yuan, yang yang, wang yan
nan yan » nan ya, wang yan, qian yan
yan jiu » yang jie, yang jin

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 yan) or (nan yan)) hua rent ((yan jiu) OR (pang jiu)) ((yong sau) or (kong saur)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wan ((yan yan) OR (nan yan)) hua rent ((yan jiu) OR (pang jiu)) ((yong sau) OR (kong saur)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan ((yan yan) or (nan yan)) hua rent ((yan jiu) OR (pang jiu)) ((yong sau) or (kong saur)) ;*".
