Laomaquanhe Border Checkpoint is located in Saga County, Shigatse City, Tibet Autonomous Region. A group of policemen with an average age of 26 are stationed here.

They are "taken care of" by strong ultraviolet rays and strong winds all year round, giving them faces that are more "mature" than their peers. "New Year" is a word that makes people happy, but for the policemen who stick to their posts, this word is tinged with a sense of helplessness and sadness.
