Perhaps you should try some spelling variations:
lean thinking » re thinking, new thinking
thinking 1 » thinking _, thinking a
song sein » song shin, song jin, song min
liang ii » liang li, liang wei, liang zhi
kann ein » kann eine, kann die, kann man
wai yan » wei yang
ii lean » ii legal, mit lean

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: ((wai yan) OR (wang yan)) liang ii lean thinking 1 ((kann ein) OR (song sein)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wai yan) OR (wang yan)) liang ii lean thinking 1 ((kann ein) or (song sein)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((wai yan) OR (wang yan)) liang ii lean thinking 1 ((kann ein) or (song sein)) ;*.
