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