Base on what you found, some thing still not right.
Have you got power back after you fix up the short? Not thing to worry about if power is back on after it got fixed.
Check it again, make sure the "black" or the "red" not shorted to white or ground( bare copper wire)
白线和GROUND should have a connection, they are connected throught the "Earth ground", Earth ground means the actual "Earth". phyically they are not connected at your breaker panel, However the "White" wire is connected to the "Earth ground" at the power station or the out side transformer.
The uninsulated copper wire is there draining the electricity to "Earth" in case "electrical leakage" from the appliance,it is connected to the metal breaker panel
The white wire is the return path back to out side tranformer then connect to Earth ground, (there for these two wire, the white and uninsulated copper wire is some how connected)
