Why did the Public Security Bureau let 12320 call?

The reason why the Public Security Bureau asked 12320 to call is as follows:

On December 28, Guangdong Province officially launched the 12320 investigation number for people at risk of the epidemic. From now on, people at risk of the epidemic must complete the declaration of entry to Guangdong in the "Guangdong Provincial Affairs" applet before entering Guangdong, and pay attention to answering and checking the 12320 special number calls and text messages.

Before entering Guangdong, persons at risk of the epidemic should take the initiative to complete the declaration of entry to Guangdong through the "Guangdong Province Affairs" mini-program. Persons at risk of the epidemic can open the "Guangdong Provincial Affairs" applet, select the "Declaration for Entry to Guangdong" module, then select the category to which they belong, and follow the guidelines to declare for entry into Guangdong. For groups such as the elderly and children who are inconvenient to use mobile phones, family members and community workers can declare on their behalf.

After the application is completed, the 12320 special number will remind you to pay attention to the calls made by the 12320 special number through intelligent voice and text messages, remind you to take personal protection, and inform you of precautions when entering Guangdong. Grassroots staff at the destination will contact those at risk of the epidemic through the special number 12320 to verify personal declaration information.
