Perhaps you should try some spelling variations:
lean thinking » re thinking, new thinking
thinking four » thinking form, thinking about, thinking aloud
yan liang » yang liang, wang liang, you liang
song skin » song shin, song jin
liang li » ling li, qiang li, liang wei
kann ein » kann eine, kann die, kann man
song min » song ming, gong min, jong min
li lean » ii lean, li lan, mit lean
wang » wing, wan, lang

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 yan liang li lean thinking four ((kann ein) OR (((song skin) OR (song min)))) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yan liang li lean thinking four ((kann ein) or (((song skin) OR (song min)))) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yan liang li lean thinking four ((kann ein) or (((song skin) OR (song min)))) ;*.
