Why can't express delivery reach Jiru Village, Gamba County?

Hello, I want to ask why the express delivery can't reach Jiru Village, Gamba County. The main reasons why express delivery cannot reach Jiru Village in Gamba County are:

1. Jiru Village, Gamba County is located in the southeast of Gamba County, Naqu City, Xizang Autonomous Region, and belongs to a remote and cold mountainous area. The steep terrain, complicated road conditions, changeable weather and cold climate all make express delivery difficult.

2. In addition, due to the remoteness of Jiru Village in Gamba County, the logistics and transportation facilities are relatively backward, and the logistics service is lagging behind, resulting in a relatively long delivery time for express delivery to this area.
