青浦全力备战进博会 - 2020年10月30日

Qingpu District is in full gear for the third China International Import Expo as the clock ticks down to the start of the event, authorities announced on Thursday.
A "grid-management" platform that relies on surveillance cameras will ensure that any problems are tackled efficiently, they said. The system combines online and offline patrols.
