Perhaps you should try some spelling variations:
thinking four » thinking form, thinking about, thinking aloud
yan ling » yan liang, yang liang, yang jing
kann ein » kann eine, kann die, kann man
wan yan » wang yan, nan yan, wai yan
li land » ii land, i land, die land
li lan » lai lan, li lin, li nan
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 ling ((li land) OR (li lan)) thinking four ((kann ein) OR (song shin)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan yan ling ((li land) OR (li lan)) thinking four ((kann ein) or (song shin)) ;~".
• Adding a wildcard symbol may retrieve word variants: wan yan ling ((li land) OR (li lan)) thinking four ((kann ein) or (song shin)) ;*.
