The History of Liao Dynasty is mainly based on Ye Lu Yan's Records of the Imperial Dynasty and Chen Daren's History of Liao Dynasty, taking its essence as the blueprint. The materials of Jinshi and Songshi are richer than Liao History. The compilation of three histories is the crystallization of the work of historians of all ethnic groups. In the twenty-four history of China, it is rare for so many minority historians to take part in compiling history.
The three histories are compiled according to the official history style of past dynasties, that is, they are divided into Ji, Zhi and Biao Chuan, but Ji, Zhi and Biao have their own characteristics. This is because these three regimes have their own characteristics. For example, Wei Yingzhi and Tribe Table in Liao History are lacking in traditional history books. Another example is that the history of Liao and Jin Dynasties is accompanied by a volume of Interpretation of Mandarin, which is unique in the traditional twenty-four histories, because the language and characters of Qidan and Jurchen nationality are gradually unknown to people. Therefore, this part of the content has become valuable materials for studying the Khitan and Jurchen scripts today.
Although these three histories were completed in just two and a half years, they basically reflect the historical truth of these three regimes because of their rich materials, ready-made materials and correct compilation methods. However, due to the short compilation time, there are some inaccuracies in the selection of materials, and also some obvious mistakes, such as two biographies by one person, inconsistent biographies, different translated names and different histories. In addition, the Yuan rulers also deleted many unfavorable materials, such as the early relationship between Jin and Mongolia, which is unknown to future generations.
