When Du Heng quit his job and set foot on the Sichuan-Tibet line alone, he had no intention of coming back alive. He thought this journey was just to say goodbye, but he met Gu Weixi on the way. She is bright, stubborn and loves to laugh, like an untimely fire in the thin air of the plateau. From strangers to peers, they saw wind and snow, sunshine and countless silent nights on the way over mountains and ridges, and they also saw each other's hidden lives bit by bit. Du Heng originally thought that he was accompanying her for a while, but later he realized that she was the one who brought him back to the world bit by bit from the wilderness. It's just that some people come into your life, not to accompany you after you arrive, but to teach you what nostalgia is.
Intention: When someone is being saved by someone else, is he being saved by you?
