Perhaps you should try some spelling variations:
lean thinking » re thinking, new thinking
thinking a » thinking _
wang yang » wang yan, wang liang, wang yanling
wan yang » dan yang, tan yang, yang yang
qiang li » liang li, qiang niu, ling li
kann ein » kann eine, kann die, kann man
li lean » ii lean, li lan, 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) OR (wang yang)) qiang li lean thinking a ((kann ein) OR (song shin)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wan yang) OR (wang yang)) qiang li lean thinking a ((kann ein) or (song shin)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((wan yang) OR (wang yang)) qiang li lean thinking a ((kann ein) or (song shin)) ;*.
