Perhaps you should try some spelling variations:
case deals » close deals, case das, case des
deals how » deal how, seals how, goals how
fang yuan » wang yuhan, meng yuan, tang yun
one case » some case, one class, one phase
yang jin » yang jie, yang jun, ying jin
yang jui » yang judy, yang xi, yang yi
how co » how cios, how ceos, how cool

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: one case deals how co ((((yang jin) OR (wang yan))) OR (yang di)) ((fang yuan) OR (yang jui)) ;~.
• Adding a wildcard symbol may retrieve word variants: one case deals how co ((((yang jin) or (wang yan))) or (yang di)) ((fang yuan) or (yang jui)) ;*.
