Perhaps you should try some spelling variations:
wang yang » wang yan, wang liang, wang yanling
wien rene » wie rene
wien eine » wie eine, wien die
ran ying » fan ying, tan ying, jin ying
yang thi » dang thi, yang chik, yang di
thi hong » tan hong
hong hai » shang hai, zhong tai, dang hai

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