Perhaps you should try some spelling variations:
china wang » china yang, china chang, china zhang
chin fang » chin chang, china yang, cai fang
shang kai » shang hai
wei shen » kwei sheng, enwei shen, wei shang
yang jui » yang judy, yang di, yang yi
yi gang » ii gang, i gang, li gang
yang xi » yang di, yang yi

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