Perhaps you should try some spelling variations:
von sprach » von sprache, von sprachen
wang dong » wang yong, wang hong, wang jing
wang yang » wang yan, wang liang, wang yanling
yang hui » yang jui, wang hui, yang muxi
von sach » von fach, von sa, von sam
ren pan » ren yan
pan ji » ban ji, pan di, san ji

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((wang dong) OR (wang yang)) ((yang hui) or (yang di)) ren pan ji ((von sach) or (von sprach)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang dong) OR (wang yang)) ((yang hui) OR (yang di)) ren pan ji ((von sach) OR (von sprach)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang dong) OR (wang yang)) ((yang hui) or (yang di)) ren pan ji ((von sach) or (von sprach)) ;*".
