Perhaps you should try some spelling variations:
wan china » can china, dan china, wuhan china
han china » hang china, than china, can china
shang kai » shang hai
zhang su » chang su, zhang si, zhang shuo
yang jui » yang judy, yang di, yang xi
yang jun » pang jun, yang jin, yang judy
su chen » su cheng, yu chen, jui chen
yang yi » yang di, yang xi

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 china) OR (han china)) zhang su chen ((((yang jui) OR (yang jun))) OR (yang yi)) shang kai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wan china) OR (han china)) zhang su chen ((((yang jui) or (yang jun))) or (yang yi)) shang kai ;~".
• Adding a wildcard symbol may retrieve word variants: ((wan china) OR (han china)) zhang su chen ((((yang jui) or (yang jun))) or (yang yi)) shang kai ;*.
