Historiography is the carrier of cultural inheritance. For example, Historical Records is the first biographical history book in China, which describes in detail the history of about 3,000 years from the Yellow Emperor to the first year of the founding of Emperor Wu of Han Dynasty, and has become an important reference for future generations to study the ancient history of China. Historiography is the guiding ideology of governing the country. Taking Zi Tong Zhi Jian as an example, it summarizes the law of the rise and fall of dynasties, integrates Sima Guang's evaluation of dynasties and his philosophy of doing things, and provides important ideological and political guidance for future generations. Historiography is also an important channel for cultural inheritance. As the largest official revised series in ancient China, Sikuquanshu collected the essence of various ancient books and collected a large number of different types of history books, which provided extensive and in-depth research materials for later scholars.
