Perhaps you should try some spelling variations:
drei formen » die formen, durch formen
wang liang » wang yang
der formen » der reformen, die formen, der form
david hong » david ng
von david » john david, ben david, jan david
wan wang » wen wang, yan wang, wang yang
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: wan wang liang ((((drei formen) OR (zwei formen))) OR (der formen)) von david hong hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan wang liang ((((drei formen) OR (zwei formen))) or (der formen)) von david hong hai ;~".
• Adding a wildcard symbol may retrieve word variants: wan wang liang ((((drei formen) OR (zwei formen))) or (der formen)) von david hong hai ;*.
