Cheng Yanqiu wrote this opera based on Liu Shang’s Hujia Shiba Pai, a series of songs about the life of Cai Yan.
Li Que, Guo Si and Yang Feng attempt to overthrow Emperor Xian of Han (Liu Xie). Meanwhile, King of the Southern Xiongnu state seizes the opportunity of general disorder and sends Zuo Xianwang and Bai Boshuai to invade inner Han territories. Minister Cai Yong’s daughter, Cai Yan (Wenji) flees from calamity, but Zuo Xianwang captures her. After relocating in Xiongnu land, Cai Wenji becomes Zuo’s concubine and bears him two sons.
Twelve years later, Han minister Cao Cao finds out that Cai Wenji lives in the Xiongnu state, and dispatches envoy Zhou Jin to claim her back. Cai Yan loves her husband, but as a patriot she feels compelled to go. She visits Wang Zhaojun’s tomb, another political bride, and cries bitterly. At the border of the two states, she bids farewell to her sons, and finally returns to her home country.
