Perhaps you should try some spelling variations:
lean thinking » re thinking
new thinking » re thinking
wang yang » wang yan, wang liang, wang yanling
yang jing » wang jing, yang jin, huang jing
kann ein » kann eine, kann die, kann man
jing li » jing ji, ling li, jing jia
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 yang jing li ((lean thinking) OR (new thinking)) form ((kann ein) OR (song shin)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yang jing li ((lean thinking) OR (new thinking)) form ((kann ein) or (song shin)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yang jing li ((lean thinking) OR (new thinking)) form ((kann ein) or (song shin)) ;*.
