Perhaps you should try some spelling variations:
lean thinking » re thinking, new thinking
land thinking » brand thinking, can thinking, mind thinking
yang liang » wang liang, yan liang, yang yang
liang zhi » liang zhu, wang zhi, liang li
wei yang » pei yang, wei wang, wei yang's
kann ein » kann eine, kann die, kann man
song min » song ming, gong min, jong min

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: wei yang liang zhi ((land thinking) OR (lean thinking)) form ((kann ein) OR (song min)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wei yang liang zhi ((land thinking) OR (lean thinking)) form ((kann ein) or (song min)) ;~".
• Adding a wildcard symbol may retrieve word variants: wei yang liang zhi ((land thinking) OR (lean thinking)) form ((kann ein) or (song min)) ;*.
