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