Perhaps you should try some spelling variations:
und reformen » und formen, und reform, und normen
der reformen » der reform
beim david » kim david
david hong » david ng
yan liang » yang liang, wang liang, you liang
hong ghi » zhong zhi, hong g, hong hai
wan yan » wang yan, nan yan, wai yan

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "wan yan liang ((und reformen) OR (der reformen)) beim david hong ghi ;~".
• Adding a wildcard symbol may retrieve word variants: wan yan liang ((und reformen) OR (der reformen)) beim david hong ghi ;*.
