Perhaps you should try some spelling variations:
wang yang » wang yan, wang liang, wang yanling
shang hai » shang kai, dang hai, chang ha
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 tin » yang jin, yang lin, yang jing
hong hai » zhong tai, dang hai, hong tan

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 tin ((hong hai) OR (shang hai)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yang) or (ran ying)) yang wie rene yang tin ((hong hai) OR (shang hai)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang yang) or (ran ying)) yang wie rene yang tin ((hong hai) OR (shang hai)) ;*.
