Perhaps you should try some spelling variations:
land thinking » brand thinking, can thinking, mind thinking
lean thinking » re thinking, new thinking
yan qiang » yan liang, yang liang, dan qing
qiang ii » qiang li, qiang niu, qian yi
bonn ein » bonn mein, bonn die, kann ein
song min » song ming, gong min, jong min
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 qiang ii ((land thinking) OR (lean thinking)) form ((bonn ein) OR (song min)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan yan qiang ii ((land thinking) OR (lean thinking)) form ((bonn ein) or (song min)) ;~".
• Adding a wildcard symbol may retrieve word variants: wan yan qiang ii ((land thinking) OR (lean thinking)) form ((bonn ein) or (song min)) ;*.
