Perhaps you should try some spelling variations:
wang liang » wang yang
wei formen » zwei formen, drei formen, der formen
formen die » formel die, former die, reformen die
liang wei » xiang wei, zhang wei, wang wei
die david » de david, dawe david, time david
yan wang » yuan wang, yang yang, qian wang
hong hai » shang hai, zhong tai, dang hai
ng hai » 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: yan wang liang wei formen die david ((((ng hai) OR (hong hai))) OR (da((ng hai) OR (hong hai)))) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "yan wang liang wei formen die david ((((ng hai) OR (hong hai))) or (da((ng hai) OR (hong hai)))) ;~".
• Adding a wildcard symbol may retrieve word variants: yan wang liang wei formen die david ((((ng hai) OR (hong hai))) or (da((ng hai) OR (hong hai)))) ;*.
