Perhaps you should try some spelling variations:
china yang » china ying, china wang, china chang
chin fang » chin chang, china wang, cai fang
shang kai » shang hai
yang jui » yang judy, yang di, yang xi
yang jin » yang jie, yang jun, ying jin
yang yi » yang di, yang xi
yi chen » jui chen

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