Perhaps you should try some spelling variations:
cost planning » forest planning
planning can » planning chain, planning case, planning land
china going » chia going, china ying, china jiing
china main » china's main, china may
china gain » china grain, china plain
lin shang » bin zhang, jin chang, xia shang
shang hai » shang kai, dang hai, chang ha
yang lin » yang jin, wang lin, yang li

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: cost planning can ((((china main) OR (china gain))) OR (china going)) yang lin shang hai ;~.
• Adding a wildcard symbol may retrieve word variants: cost planning can ((((china main) or (china gain))) or (china going)) yang lin shang hai ;*.
