Perhaps you should try some spelling variations:
lean thinking » re thinking, new thinking
thinking a » thinking _
yan liang » yang liang, wang liang, you liang
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 » wang 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 liang ii lean thinking a ((kann ein) OR (song sein)) ;~.
• Adding a wildcard symbol may retrieve word variants: wai yan liang ii lean thinking a ((kann ein) or (song sein)) ;*.
