Perhaps you should try some spelling variations:
chain what » brain what, chain has, champion what
what brain » what again
man chain » gas chain, a chain, man can
yan liang » yang liang, wang liang, you liang
dang hari » dang hai
wenn man » kann man, wenn das
yang jin » yang jie, yang jun, ying jin

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: wenn man chain what brain ((yan liang) OR (yang jin)) dang hari ;~.
• Adding a wildcard symbol may retrieve word variants: wenn man chain what brain ((yan liang) or (yang jin)) dang hari ;*.
