Heavy fog blocks the entry and exit of a large number of international ships in Shanghai's main port area. On the 17th, nearly 50 international sailing ships within the jurisdiction of Waigaoqiao Border Inspection Station postponed or canceled their original berthing and sailing plans.

The border inspection department has strengthened video surveillance and inspection of terminal personnel’s vehicles to effectively prevent risks and hazards. It also properly maintains ship dredging and port order, and strives to reduce navigation delays due to fog.
