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