Perhaps you should try some spelling variations:
land thinking » brand thinking, lean thinking, can thinking
thinking four » thinking form, thinking about, thinking aloud
yang qiang » yang liang, yang yang, gong qiang
wang liang » wang yang
bonn ein » bonn mein, bonn die, kann ein
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) OR (wang liang)) ii land thinking four ((bonn ein) OR (song shin)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yang qiang) OR (wang liang)) ii land thinking four ((bonn ein) or (song shin)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((yang qiang) OR (wang liang)) ii land thinking four ((bonn ein) or (song shin)) ;*.
