Perhaps you should try some spelling variations:
lean thinking » re thinking, new thinking
thinking four » thinking form, thinking about, thinking aloud
yang qiang » yang liang, wang liang, yang yang
wang yang » wang yan, wang liang, wang yanling
qiang li » liang li, qiang niu, ling li
bonn ein » bonn mein, kann ein, bonn iii
bonn die » kann die, wenn die
li lean » ii lean, li lan, mit lean
shin » skin, sein, thin

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 yang qiang li lean thinking four ((((bonn ein) OR (bonn die))) OR (song shin)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yang qiang li lean thinking four ((((bonn ein) OR (bonn die))) or (song shin)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yang qiang li lean thinking four ((((bonn ein) OR (bonn die))) or (song shin)) ;*.
