The electronic tag body includes a housing, a display screen configured to display information, and a sensor and a main controller that are disposed inside the housing. The sensor is configured to detect an ambient temperature of an environment in which the electronic tag body is located. The main controller is configured to shut off power supplied to the display screen in response to the ambient temperature detected by the sensor being beyond an operating temperature range of the display screen.
