As this was a situation where communication was not convenient, the military depot only knew that they had lost contact with 20 people. They did not know the outcome of the rescue, so they continuously sent people over to provide support to ensure everyone's safety.
The communication base station and satellite base station in the northwest of the border were all entering the final phase of the project. By June or so, communication between the various military depots could be maintained through the satellite base stations even if there was a blizzard.
If anything happened to the trucks driving along the Tibetan Line, they could immediately contact the various military depots via satellite phones and request help.
