Phuntsog Tashi, from Qamdo County, Qamdo Prefecture, is a guardian of the "heavenly road". No matter it rains or snows, he sticks to his own position along the toughest railway region everyday, and he hardly has any time to stay with his parents, wife and children. His mother said, "my son is guarding thousands of families' happiness instead of the cold railway." Photo shows that Phuntsog Tashi is inspecting and repairing the railway side fence.
