In this 100-chapter novel, Chu Renhuo’s primary aim is to demonstrate that the rise of the Tang dynasty was mandated by heaven. The original readers would have understood that the author subtly contrasts this against the rulers of his day, drawing the conclusion that the Qing dynasty did not have the right to rule over China.
The author includes Mulan’s story as a subplot of a novel which condemns imperialism. Mulan is heralded as a hero who fiercely resists a cruel tyrant. Chu Renhuo concludes Mulan’s story with a tragic ending to comment on the wrongdoing committed by the Manchu under whom he was forced to serve. In this novel, the Chinese are depicted as wonderfully benevolent, while the non-Chinese are evil.
Mulan’s story begins in chapter 56 of Romance of Sui and Tang. The Tujue khan issues a draft for more men; Mulan’s father is among those who are conscripted. Mulan, a biracial (Tujue-Chinese) teenage girl, dresses as a man and volunteers to take her father’s place to fight on behalf of the Tujue-Chinese alliance.
The Tujue army is defeated. Mulan rescues the khan but is captured by Dou Xianninang, Princess of Xia. The princess, who is Han Chinese, is such a generous and loving captor that Mulan discloses her true identity to the princess, and the two become sworn sisters. Soon, Princess Xianniang’s father, Dou Jiande, is captured by the Chinese and is about to be executed. Both the princess and Mulan go before the Chinese Emperor Taizong with knives in their mouths, expressing their desire to risk their own lives to beg that Xianniang’s father be allowed to live. The emperor is so impressed that Dou Jiande is released.
During a previous battle, a Chinese soldier had been rescued, who holds an undelivered letter from the Chinese warlord Luo Cheng. Princess Xianniang is overjoyed to discover that the letter, addressed to a matchmaker, asks for the Xianniang’s hand in marriage. Even though Luo Cheng and Princess Xianniang are secret lovers, they are fighting on opposite sides. When the princess’ father is captured by the Chinese, she becomes certain that the wedding will never take place.
Princess Xianning composes a tearful letter to Luo Cheng and asks Mulan to deliver it on her behalf when she returns home. Mulan sets out but promises that she will return and bring her family back with her. Mulan arrives home but is devastated to find that her father has passed away, and her mother has already remarried. When the khan hears that Mulan is a woman, he no longer feels that he owes her his life; instead, he is determined to take her as his concubine. Mulan asks to see her father’s grave before submitting to the khan’s demands. There, she slits her own throat, declaring that she will be loyal to no man other than her father.
Before her death, Mulan had entrusted Princess Xianniang’s letter to her sister, Youlan. Youlan dresses as a male scholar and delivers the letter to Luo Cheng.
One day, Luo Cheng overhears some of the female servants gossiping and discovers that Youlan is, in fact, a woman. He approaches Youlan and asks her to “prove” her masculinity by sleeping with him in the same bed. When Youlan hesitates, Luo Cheng insists that it is entirely appropriate for two men to share a bed.
Several months later, Princess Xianniang discovers that Luo Cheng and Youlan have been sleeping together. She summons Youlan and shows her a magical jade pendant, which can verify whether a young girl is still a virgin. When Youlan passes the test, Xianniang is touched to discover that Luo Cheng was not intimate with Youlan; she concludes that Luo Cheng must still has strong feelings for the princess.
Luo Cheng takes both Xianniang and Youlan to be his brides, and a joyful wedding is celebrated.
