china's tour » china's court, china's top, china's third
yanling can » banking can, planning can
shang hai » shang kai, dang hai, chang ha
xi shang » xia shang, xi zhang, wei shang
yang xi » yang di, yang yi, yang jui

• If you are trying to use Boolean operators, they must be ALL CAPS: wan ((yanling can) OR (banking case)) ((china's tour) OR (china's gdp)) yang xi shang hai ;~.
• Adding a wildcard symbol may retrieve word variants: wan ((yanling can) or (banking case)) ((china's tour) or (china's gdp)) yang xi shang hai ;*.
