Perhaps you should try some spelling variations:
ansatze zhu » ansatze zur, ansatze zum, ansatzes zur
ansatze zu » ansatze zur
yan guang » yang guang, yan guan, gan guan
guang die » guang zhe, huang di, klang die
zhong tai » hong tan, hong hai, zhong zhi
nan yan » nan ya, wang yan, qian yan
dong di » dong sin

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 zhu) OR (ansatze zu)) ji ((zhong tai) OR (dong di)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "nan yan guang die ((ansatze zhu) OR (ansatze zu)) ji ((zhong tai) or (dong di)) ;~".
• Adding a wildcard symbol may retrieve word variants: nan yan guang die ((ansatze zhu) OR (ansatze zu)) ji ((zhong tai) or (dong di)) ;*.
