Legend of the Demon Cat

Lore & Background

The film opens in AD 805 in Chang’an, where Chunqin, wife of imperial guard commander Chen Yunqiao, shares a pear with a talking black cat and receives a pot of coins. Meanwhile, Japanese monk Kūkai is summoned to exorcise Emperor Dezong, who dies amid a cat’s wail. Court scribe Bai Letian is ordered to record the death as illness. Kūkai and Bai discover a floating wooden tablet threatening the crown prince, and Bai later retrieves a lock of Lady Yang’s hair from the cat's lair under a tree, believing it proves Emperor Xuanzong’s everlasting sorrow.

The demon cat attacks Chen Yunqiao and possesses his wife, revealing it was Xuanzong’s pet, buried alive on the emperor’s orders—an act carried out by Chen’s father. The cat escaped but later died from being buried alive, with poisoned fish as a secondary cause. Its resentment festered into a vengeful spirit. The film also reveals that Lady Yang was not strangled by Gao Lishi; instead, a eunuch under orders performed the strangling, while Gao Lishi administered an acupuncture-induced death-like sleep.

Reader's Guide

Legend of the Demon Cat offers a surreal reimagining of one of China’s most famous historical romances, blending fantasy, mystery, and historical tragedy. The film’s significance lies in its exploration of how power, love, and betrayal intersect, as the demon cat’s revenge exposes the hidden truth behind Lady Yang’s death. By framing the story through the investigative partnership of Bai Letian and Kūkai, the film examines the nature of historical record and poetic memory, contrasting official accounts with buried realities. The cat’s perspective challenges the romanticized version of the emperor’s sorrow, revealing a more complex and brutal narrative. The film also highlights the role of outsiders—a Japanese monk and a court scribe—in uncovering suppressed history. Its legacy includes its visual spectacle and its adaptation of Baku Yumemakura’s novel, contributing to cross-cultural storytelling between China and Japan. The film premiered in China on December 22, 2017, and remains notable for its ambitious narrative structure and its meditation on the cost of imperial power.

A Sino-Japanese Fantasy Reimagining

Legend of the Demon Cat (Yāomāo chuán) stands as a striking example of cross-cultural cinematic collaboration, uniting Chinese director Chen Kaige with the Japanese literary world. The film adapts Baku Yumemakura's novel series into a surreal fantasy mystery set against the backdrop of the Tang dynasty. Its central premise reimagines the well-known tragic romance between Emperor Xuanzong and his beloved consort Lady Yang, filtering that historical love story through the lens of supernatural investigation and political intrigue during the devastating An Lushan Rebellion. The project brought together a bilingual cast: Huang Xuan portrays Bai Letian, a court scribe driven by literary ambition, while Shota Sometani plays Kūkai, a Japanese Buddhist monk serving as a Kentōshi in the imperial capital. Their partnership forms the investigative spine of the narrative. The film premiered in mainland China on December 22, 2017, marking a significant moment in the exchange of storytelling traditions between the two neighboring nations.

The Investigative Partnership

The narrative engine of the film is the unlikely duo of Bai Letian and Kūkai, whose contrasting temperaments create a dynamic investigative partnership. Bai, a court scribe whose official role is recording the emperor's daily conduct, is characterized by his lively, straightforward energy and a burning ambition to achieve literary immortality through an epic poem called Song of Everlasting Sorrow. Kūkai, by contrast, brings a dry, measured wit; he is a Japanese monk who traveled to Chang'an as a Kentōshi hoping to study under Huiguo, abbot of the Great Qinglong Temple, only to be refused entry. Their bond crystallizes in AD 805 when, after a mysterious cat's wail accompanies the sudden death of Emperor Dezong, they are thrust into a shared mystery. A self-rising wooden tablet threatens the crown prince's life, and Bai's initial skepticism—having never seen a cat in three years of palace service—gives way to collaboration. Together they wander the bustling streets of Chang'an, drawn by street magicians' illusions and the rumors of a supernatural creature haunting the household of imperial guard commander Chen Yunqiao.

The Mawei Station Tragedy

Beneath the film's supernatural surface lies a harrowing political tragedy rooted in the An Lushan Rebellion of AD 756. As the imperial court fled Chang'an for Chengdu, mutinous guards under Chen Xuanli pinned the blame for the uprising on Lady Yang, believing her beauty had seduced An Lushan and inflamed his ambitions. They executed members of her family, including her cousin Yang Guozhong, to force Emperor Xuanzong's hand. The emperor found himself trapped in an impossible political bind: surrendering his consort to the troops would destroy his authority, compelling her to take her own life would equally undermine his dignity, and the proposal—advanced by the Japanese Kentōshi Abe no Nakamaro—to smuggle her to Japan would, if discovered, provoke the soldiers and doom the emperor as well. In the end, Gao Lishi, Xuanzong's longtime eunuch attendant, strangled Lady Yang on the emperor's direct orders. An elderly former lady-in-waiting, who had woven the white silk used for the killing, recounts this to the investigators. The demon cat then silences her for her complicity, ensuring the truth remains buried.

The Cat as Witness and Avenger

The demon cat is far more than a supernatural set piece; it functions as the film's ultimate truth-teller and a vessel of unresolved grief. Originally Emperor Xuanzong's pet, the cat was present at the Feast of Supreme Joy, Lady Yang's birthday banquet in AD 755, where it witnessed firsthand that Li Bai's celebrated poem praising the consort was composed before the poet ever met her. The cat's tragic fate sealed its transformation: on Xuanzong's orders, it was buried alive, an act carried out by Chen Xuanli. It escaped the grave, later arrived at the Chen household seeking vengeance, and died after consuming poisoned fish. Its unextinguished resentment crystallized into a demonic spirit bound to a single purpose—collecting debts from the Tang royal house and the Chen family. The cat possesses Chunqin, drives Chen Yunqiao into madness, and eliminates the elderly lady-in-waiting. Through its violent acts and its declarations that debts must be paid, the creature dismantles the romantic mythology surrounding Lady Yang, insisting that the poetry and legends are false and that the truth of her death belongs to no one but the one who was silenced.
