Perhaps you should try some spelling variations:
yuan ping » yuan ming, yuan ting, yuen ping
went siu » wenn sie, tent six
wong siu » wong shiu, kong siu, wong sau
dong di » dong sin
ya yuan » yan yuan
ping ku » ping ke, ping yu
ku ying » ka ying, ku ring, hui ying
wang » wan

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 wing) OR lang) yan) OR (dong di)) ya yuan ping ku ying ((went siu) OR (wong siu)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((wang or wing) or lang) yan) or (dong di)) ya yuan ping ku ying ((went siu) OR (wong siu)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((((wang or wing) or lang) yan) or (dong di)) ya yuan ping ku ying ((went siu) OR (wong siu)) ;*.
