based thinking » case thinking, shared thinking, based training
thinking firm » thinking form, thinking from, thinking circa
lang yanling » wang yanling, wang yangming, zhang yunling
zwang als » zugang als, wang all, zwang des
klang als » klang amp
song sein » song shin, song jin, song min
bonn ein » bonn mein, bonn die, kann ein

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: lang yanling ((zwang als) OR (klang als)) based thinking firm ((bonn ein) OR (song sein)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang yanling ((zwang als) OR (klang als)) based thinking firm ((bonn ein) or (song sein)) ;~".
• Adding a wildcard symbol may retrieve word variants: lang yanling ((zwang als) OR (klang als)) based thinking firm ((bonn ein) or (song sein)) ;*.
