Perhaps you should try some spelling variations:
thinking form » thinking firm, thinking from, thinking before
thinking four » thinking about, thinking aloud, thinking from
yan ling » yan liang, yang liang, yang jing
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 li lean ((thinking form) OR (thinking four)) ((kann ein) OR (song shin)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yan ling li lean ((thinking form) OR (thinking four)) ((kann ein) or (song shin)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yan ling li lean ((thinking form) OR (thinking four)) ((kann ein) or (song shin)) ;*.
