It is dangerous to interchange the connection of LIVE (活線) and NEUTRAL wires (中線). In general, the switch of an electrical appliance is connected to the LIVE wire. Should the LIVE wire connection is interchanged with that of the NEUTRAL wire, the appliance would be at LIVE voltage even when the switch is open. This easily leads to electrical shock, which may be fatal.
