Perhaps you should try some spelling variations:
thinking form » thinking from, thinking four, thinking before
thinking firm » thinking from, thinking circa, thinking big
yang liang » wang liang, yan liang, yang yang
kann eine » kann ein, dann einen, kann die
song skin » song shin, song jin, song min
wan yang » wang yang, dan yang, tan yang
liang li » ling li, qiang li, liang wei
li lan » lai lan, li lin, li nan

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 yang liang li lan ((thinking form) OR (thinking firm)) ((kann eine) OR (song skin)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan yang liang li lan ((thinking form) OR (thinking firm)) ((kann eine) or (song skin)) ;~".
• Adding a wildcard symbol may retrieve word variants: wan yang liang li lan ((thinking form) OR (thinking firm)) ((kann eine) or (song skin)) ;*.
