Perhaps you should try some spelling variations:
thinking john » thinking can, thinking form, thinking four
yang liang » wang liang, yang yang, peng liang
yan liang » wang liang, you liang, yan wang
song thin » song shin, song jin, song min
kann ein » kann eine, kann die, kann man
i re » i rep, _ re, i e

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) OR (yan liang)) i re thinking john ((kann ein) OR (song thin)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan ((yang liang) OR (yan liang)) i re thinking john ((kann ein) or (song thin)) ;~".
• Adding a wildcard symbol may retrieve word variants: wan ((yang liang) OR (yan liang)) i re thinking john ((kann ein) or (song thin)) ;*.
