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

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