Perhaps you should try some spelling variations:
thinking form » thinking firm, thinking from, thinking before
thinking four » thinking about, thinking aloud, thinking from
yan liang » yang liang, wang liang, you liang
liang li » ling li, qiang li, liang wei
wai yan » wang yan, wei yang
li land » ii land, i land, li lan

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: wai yan liang li land ((thinking form) OR (thinking four)) ((kann man) OR (shang jin)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wai yan liang li land ((thinking form) OR (thinking four)) ((kann man) or (shang jin)) ;~".
• Adding a wildcard symbol may retrieve word variants: wai yan liang li land ((thinking form) OR (thinking four)) ((kann man) or (shang jin)) ;*.
