The historical story told in The Romance of Sui and Tang Dynasties began when Emperor Wen of Sui Dynasty destroyed Chen and ended when the Anshi Rebellion was put down. Tang Xuanzong returned to Chang 'an from Shu and died in the west. Judging from the structure of the book, it mainly tells three stories: first, the heroic legends of Qin Qiong, Xu Maogong, Cheng, Li Jing, Weichi Gong and Luo Cheng against Sui and Tang Dynasties; The second is the story of the imperial palace in the Sui Dynasty, in which the emperor killed his father and usurped the throne, subjugating the country and destroying the species. Thirdly, Li Shimin, Emperor Taizong, took in the heroes who fought against Sui Dynasty, and Xuanwumen killed his brother and seized power, which created the martial arts and civil administration in the prosperous Tang Dynasty (which greatly changed the situation that Yuan became emperor), and the tragic ending of the Anshi Rebellion caused by the love of Emperor Xuanzong of Tang Dynasty for Yang Guifei. The Romance of Sui and Tang Dynasties generally reflects the complicated social life of Sui and Tang Dynasties for more than 170 years, portrays and praises heroes, righteous men, wise kings, loyal ministers, brave generals, ladies and many other figures, especially praises the chivalrous behavior of rebellious heroes against tyranny, focuses on the love affair between Emperor Jingchang and Emperor Xuanzong of Tang Dynasty, and exposes and satirizes the extravagant and decadent life of feudal emperors. The narrative in the book is vivid, the language is fluent, and the characters are vivid, such as poverty and poverty. Dou Xianniang's "forced marriage", especially the "devil incarnate" Cheng in the Wagangzhai heroes' association, her bravery and fighting skill, Dan, who vowed to take revenge to death, and Weichi Gong, who is resourceful and straightforward, are all vividly portrayed.
