Perhaps you should try some spelling variations:
lean thinking » re thinking, new thinking
yang liang » wang liang, yan liang, peng liang
thinking a » thinking _
yang yang » wang yang, wang yan
kann ein » kann eine, kann die, kann man
ii lean » ii legal, mit lean
shin » skin, sein, thin

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: wan ((yang liang) OR (yang yang)) ii lean thinking a ((kann ein) OR (song shin)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan ((yang liang) OR (yang yang)) ii lean thinking a ((kann ein) or (song shin)) ;~".
• Adding a wildcard symbol may retrieve word variants: wan ((yang liang) OR (yang yang)) ii lean thinking a ((kann ein) or (song shin)) ;*.
