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, yan liang
zhong zhi » zhang zhi, hong ghi, zhong tai
gan guan » yan guan, quan guan, fan guon
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) OR (gan guan)) die ansatze im ji ((zhong zhi) OR (dong di)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "nan ((yan guang) OR (gan guan)) die ansatze im ji ((zhong zhi) or (dong di)) ;~".
• Adding a wildcard symbol may retrieve word variants: nan ((yan guang) OR (gan guan)) die ansatze im ji ((zhong zhi) or (dong di)) ;*.
