There's this one line that keeps haunting me: "Youth was wonderful. Sometimes it made people fearless. Sometimes it made them reckless. Most of the time, it made them both." It feels like the thesis statement for the whole novel. Lin Mo is twenty-one, she's traveling alone to places she's only read about in poetry, and she's doing it because something inside her decided she couldn't wait anymore. But the altitude metaphor is everywhere. Litang is four thousand meters above sea level. Every breath is effort. And yet she drags her suitcase through the streets, face pale, unable to stop looking around. The thin air mirrors this feeling of reaching for something that should be beautiful but also makes you struggle. Danzeng's story is the same metaphor in reverse — he's at sea level in his luxury apartment, surrounded by everything he worked for, and he's the one who feels strangely lonely. The prayer flags are another symbol I can't stop thinking about. They're everywhere in these chapters, fluttering in the wind, carrying prayers with every gust. The author doesn't over-explain them. They're just there, part of the landscape, like fate itself — present but invisible. And Lin Mo's obsession with Tsangyang Gyatso's poetry? That's not just backstory, it's a thematic key. This is a girl who fell in love with a place through words before she ever saw it with her own eyes. The novel seems to be asking: what happens when the poetry meets reality? When the dream becomes real and you're standing in a valley between towering cliffs, breathing thin air, wondering if it's enough? I think that's the real journey here. Not the bus rides or the hotpot, but this moment of arrival.
