FeatureFact and Fiction in the Sui-Tang Transition: The Lingyan Pavilion Officials vs. Outlaw Brotherhoods"Romance of Sui and Tang" writes this period of history as a jianghu of sworn brotherhood, martial contests, and roaming, while the "Old Book of Tang" records a different matter. The meritorious officials in the Lingyan Pavilion become greenwood brothers in the romance, and several of the most deeply rooted fierce generals are nowhere to be found in the official history; whereas a coup like the Xuanwu Gate Incident is actually written more plainly in the official history than in the romance. This piece compares the two sides, noting which volume each part comes from.
Event · 626 CEXuanwu Gate IncidentThe succession conflict between Li Shimin, Crown Prince Li Jiancheng and Li Yuanji erupted at Xuanwu Gate, reshaping early Tang politics and generations of narratives about imperial legitimacy.

History vs. fiction

The romance preserves historical facts and adds a supernatural revenge plot.

  • The official history records that he died in a coup. The Old Book of Tang, biographies of Yuchi Jingde, Qin Shubao, and Cheng Zhijie, records: 'They secretly reported to Taizong, and together with Yuchi Jingde and others, they killed Jiancheng and Yuanji.' The novel Sui Tang Romance, chapter 068, preserves the death at Xuanwu Gate but adds a supernatural revenge plot: 'Suddenly they saw Jiancheng leading Yuanji and Huang Taisui, shouting loudly: "Shimin has come, return our lives quickly!"'
