Perhaps you should try some spelling variations:
gang kong » gang gong, hong kong, king kong
yan clan » das clan, yan yuan
yan guan » gan guan, yan yuan, yang guang
kong siu » kong eiu, wong siu, dong sin
wan yan » wang yan, wai yan, wang yang
dong di » dong sin
nan yan » nan ya, wang yan, qian yan
ping xu » ling xu, ping ku, ping yu
xu gang » yu gang, zum gang, liu gang

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: ((wan yan) OR (dong di)) ((((yan clan) OR (nan yan))) OR (yan guan)) ping xu gang kong siu ;~.
• Adding a wildcard symbol may retrieve word variants: ((wan yan) or (dong di)) ((((yan clan) or (nan yan))) or (yan guan)) ping xu gang kong siu ;*.
