Perhaps you should try some spelling variations:
cwong yuen » chong yun
gain song » jin song
chong yah » chong nam, chong wan, chong yi
yan clan » das clan, yan guan, yan yuan
run gain » run pain
song lim » song li, song lina, dong liu
wong yue » wang yue, hong yu
yan can » man can, yan cong, yan guan

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 can) OR (yan clan)) run gain song lim ((((cwong yuen) or (wong yue))) or (chong yah)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wan ((yan can) OR (yan clan)) run gain song lim ((((cwong yuen) OR (wong yue))) OR (chong yah)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan ((yan can) OR (yan clan)) run gain song lim ((((cwong yuen) or (wong yue))) or (chong yah)) ;*".
