奈何桥边买红薯
[nài hé qiáo biān măi hóng shŭ]
Naidu Bridge (or 'Nihé Qiáo') in Chinese folklore is where souls cross over to the afterlife. Buying sweet potatoes there suggests a mundane, warm activity in an otherwise sorrowful or mystical place, reflecting the mix of life's ordinary moments even at significant transitions.
