Perhaps you should try some spelling variations:
die ansatze » der ansatze
ansatze im » ansatz im, ansatze zum, ansatze zu
yan guang » yang guang, gan guan, yan liang
zhong tai » hong tan, hong hai, zhong zhi
yan guan » gan guan, yan yuan, yang guang
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 (yan guan)) die ansatze im ji ((zhong tai) OR (dong di)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "nan ((yan guang) OR (yan guan)) die ansatze im ji ((zhong tai) or (dong di)) ;~".
• Adding a wildcard symbol may retrieve word variants: nan ((yan guang) OR (yan guan)) die ansatze im ji ((zhong tai) or (dong di)) ;*.
