Perhaps you should try some spelling variations:
lean thinking » re thinking, new thinking
thinking a » thinking _
liang wei » xiang wei, zhang wei, wang wei
kann eine » kann ein, dann einen, kann die
liang li » ling li, qiang li, liang zhi
wan yan » wang yan, nan yan, wai yan
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 yan ((liang li) OR (liang wei)) lean thinking a ((kann eine) OR (song shin)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan yan ((liang li) OR (liang wei)) lean thinking a ((kann eine) or (song shin)) ;~".
• Adding a wildcard symbol may retrieve word variants: wan yan ((liang li) OR (liang wei)) lean thinking a ((kann eine) or (song shin)) ;*.
