Perhaps you should try some spelling variations:
tan chia » tuan china, than china, can china
chia wen » china won, ching wen, asia wen
yang jui » yang judy, yang xi, yang yi
wong siu » wong shiu, kong siu, wong sau
yan tan » tan tan, yan clan, yan guan
von sap » von sa, von sam, von sach
wang » wing, 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 lang) yan tan chia wen ((yang jui) OR (yang di)) ((von sap) OR (wong siu)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang OR lang) yan tan chia wen ((yang jui) or (yang di)) ((von sap) or (wong siu)) ;~".
• Adding a wildcard symbol may retrieve word variants: (wang OR lang) yan tan chia wen ((yang jui) or (yang di)) ((von sap) or (wong siu)) ;*.
