Qiu Fo is a Mandarin ballad performed by Chinese singer Shiyan, whose title translates roughly as seeking Buddha and reflects its themes of devotion and unfulfilled longing. The song became widely recognised in China for its plaintive vocal and simple, memorable melody, and short clips of it later circulated on TikTok and other short-video platforms, where creators repurposed the emotional chorus for romance, nostalgia and farewell edits. Its staying power comes from that direct feeling: the melody is easy to recognise, easy to place under a visual story, and still feels sincere rather than ironic.
