Perhaps you should try some spelling variations:
lean thinking » re thinking, new thinking
land thinking » brand thinking, can thinking, mind thinking
yan liang » yang liang, wang liang, you liang
liang wei » xiang wei, zhang wei, wang wei
song min » song ming, gong min, jong min
wai yan » wang yan, wei yang

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