Perhaps you should try some spelling variations:
wang yang » wang yan, wang liang, wang yanling
dang hari » dang hai
dang hadi » dang hai
ran ying » fan ying, tan ying, jin ying
yang wie » yang jie, lang wien, yang di
wie rene » wilke rene, wie deine, wie eine
yang jin » yang jie, yang jun, ying jin

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: ((wang yang) OR (ran ying)) yang wie rene yang jin ((dang hari) OR (dang hadi)) ;~.
• Adding a wildcard symbol may retrieve word variants: ((wang yang) or (ran ying)) yang wie rene yang jin ((dang hari) or (dang hadi)) ;*.
