Perhaps you should try some spelling variations:
facing china » banking china, trading china
ming china » kong china
done using » line using, move using
yoon kian » hoon hian
kang wong » kang young
yan kian » yan liang, yan clan, yan guan
wong yue » wang yue, hong yu

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: done using ((yan kian) OR (yoon kian)) ((ming china) OR (facing china)) kang wong yue ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "done using ((yan kian) or (yoon kian)) ((ming china) OR (facing china)) kang wong yue ;~".
• Adding a wildcard symbol may retrieve word variants: done using ((yan kian) or (yoon kian)) ((ming china) OR (facing china)) kang wong yue ;*.
