Perhaps you should try some spelling variations:
yuan ping » yuan ming, yuan ting, yuen ping
gang kong » gang gong, hong kong, king kong
kong siu » kong eiu, wong siu, dong sin
dong di » dong sin
ya yuan » yan yuan
ping xu » ling xu, ping ku, ping yu
xu gang » yu gang, zum gang, liu gang
wang » wing, lang

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: (((wang OR wan) yan) OR (dong di)) ya yuan ping xu gang kong siu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((wang OR wan) yan) or (dong di)) ya yuan ping xu gang kong siu ;~".
• Adding a wildcard symbol may retrieve word variants: (((wang OR wan) yan) or (dong di)) ya yuan ping xu gang kong siu ;*.
