Perhaps you should try some spelling variations:
yuan chang » yuan cheng, huang chang, han chang
fang yuan » wang yuhan, wang yan, meng yuan
dang hadi » dang hai
tan yang » dan yang, tan ying, tan yong
ran ying » fan ying, tan ying, jin ying
yang jui » yang judy, yang yi
yang xi » 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: ((tan yang) OR (ran ying)) fang yuan chang ((((yang xi) OR (yang di))) OR (yang jui)) dang hadi ;~.
• Adding a wildcard symbol may retrieve word variants: ((tan yang) or (ran ying)) fang yuan chang ((((yang xi) or (yang di))) or (yang jui)) dang hadi ;*.
