110 is for alarm service, while 119 is for fire alarm and 122 for traffic accidents report. These three 24-hour calls are all the organs under the municipal bureau that receive the alarms given by the public. As the windows of the capital public security organ, they are open to the whole society to provide services to the public. These three calls have respective focuses.

If someplace is caught fire, you should call 119, and if some traffic accident happens, you should call 122, so that the public security organ will assign special personnel to the site in time.
