Perhaps you should try some spelling variations:
die ansatze » der ansatze
ansatze im » ansatz im, ansatze zum, ansatze zu
yan guang » yang guang, yan guan, gan guan
guang die » guang zhe, huang di, klang die
zhong zhi » zhang zhi, hong ghi, zhong tai
nan yan » nan ya, wang yan, qian yan
dong di » dong sin
im ji » im j

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: nan yan guang die ansatze im ji ((zhong zhi) OR (dong di)) ;~.
• Adding a wildcard symbol may retrieve word variants: nan yan guang die ansatze im ji ((zhong zhi) or (dong di)) ;*.
