Residents prepare for the worst
With sirens sounding across the city at 11:35am on Saturday, over 1.7 million people took part in air-raid drills.
At Hongxian Residential Community in Changning District, 250 residents evacuated their homes with the guidance of local civil defense officers.
As soon as the siren sounded, residents closed their windows, turned off the power and headed for a nearby shelter.
Despite the rain, the residents followed orders and got to the shelter quickly. Officers handed out emergency supplies to them.
After the sirens stopped at 11:58am, the officers opened the shelter and all residents returned to their homes.
