Moon over the Mountain Road moves through departure, home and two rivers. When You Are Old looks back from the fireside toward youth and the pilgrim soul. They are neither one work nor translations of each other, yet a 10:17 public double feature lets them illuminate one another.
One side is a contemporary Mandarin original; the other sets Yeats's English poem. Each keeps its language, singer, provenance and ending. The pairing is an editorial act—not an invented master or adaptation relationship.
Headlights reveal only a short stretch, while the moon crosses the whole mountain road. Over more than five minutes, Bajiao sings departure, looking back and a heart still willing to love. The Lancang and Ganges face one another across the lyric without being collapsed into one culture.
The song does not swear devotion at youth’s brightest moment. It begins beside the fire in old age, then looks back at those who loved beauty and the one who loved the pilgrim soul.
The exact public YouTube title names both Moon over the Mountain Road and When You Are Old, with a 10:17 runtime. The archive preserves it as a double feature while returning each song to its own complete recording, singer and cultural dossier.
Open the permanent film dossier and every verified return path ↗Moonlight on the road reveals distance and home; Yeats's stars receive a love that has fled. A shared image brings the songs near without inventing a shared source.
The Mandarin song advances through roads, rivers and backward glances. The English poem looks from old age into youth. One travels forward; one looks back; each melody answers its text.
Bajiao and Bollywood Male are headline virtual singers in Weiyang Sound. South Asian colour belongs to the sound design—not a claim of human nationality, community authority or restored tradition.
Editorial boundary: the two complete recordings total exactly 10:17, matching the public double-feature runtime. That supports a sequence check, not a claim of shared lyrics, melody, master or Suno parentage.
Weiyang Sound's East-West double feature: Moon over the Mountain Road 5:38 + Yeats's When You Are Old 4:39. Two complete songs, one 10:17 film, two virtual singers and no forty-five-second previews.
