A Hong Kong historical drama

Teased by hallucinations, Shu, a slacker living in a rural village, struggles with an ever-loosening grip on reality. Yet when one of his visions manifests as real, his fellow villagers come to regard him as a clairvoyant. Can Shu genuinely see into the future? Is he actually just a basket case? Or is he perhaps more lucid than he seems, and pulling a fast one on everyone?
