Perhaps you should try some spelling variations:
yuan cheng » yuan chang, huang cheng, yu cheng
ying fang » jing fang, yin fang, ying yang
fang yuan » wang yuhan, wang yan, meng yuan
shang kai » shang hai
yang jui » yang judy, yang xi
yang jun » pang jun, yang jin, yang judy
yang yi » 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: li ying fang yuan cheng ((((((yang jui) OR (yang di))) OR (yang jun))) OR (yang yi)) shang kai ;~.
• Adding a wildcard symbol may retrieve word variants: li ying fang yuan cheng ((((((yang jui) or (yang di))) or (yang jun))) or (yang yi)) shang kai ;*.
