Perhaps you should try some spelling variations:
wan china » can china, dan china, han china
shang kai » shang hai
zhang su » zhang si, zhang shuo, zhang hui
chang su » chang hsun, chang fwu, chang gui
yang jui » yang judy, yang di, yang xi
yang jun » pang jun, yang jin, yang judy
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 ((zhang su) OR (chang 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 ((zhang su) OR (chang su)) chen ((((yang jui) or (yang jun))) or (yang yi)) shang kai ;~".
• Adding a wildcard symbol may retrieve word variants: wan china ((zhang su) OR (chang su)) chen ((((yang jui) or (yang jun))) or (yang yi)) shang kai ;*.
