In the early morning of August 22, there was a sudden heavy rain in Shangluo City, which caused many base stations to be interrupted and communications were severely damaged. Among them, the Zhen An Da Ren town was the most damaged, and communications were completely blocked and became an information island.

The maintenance staff rushed to the site with the Sinosatview’s Land Mobile Station and quickly deployed the emergency communication system. At 18:15 on August 22, the maintenance staff took the lead in restoring the network service of the government at Daren Town, which provided network support for the government‘s flood control and rescue work, and strongly supported the information communication of on-site flood control command and dispatch.
