Han Shu, also known as Pre-Han Shu, was compiled by Ban Gu, a historian of the Eastern Han Dynasty. It is the first biographical dynastic history in China, and it is also one of the "twenty-four histories". Hanshu is another important historical book in ancient China after Shiji, and it is called "the first four histories" together with Shiji, Houhanshu and The History of the Three Kingdoms. Hanshu mainly describes the history of 230 years from the first year of Emperor Gaozu of the Western Han Dynasty (206 BC) to the fourth year of Emperor Wangmang of the New Dynasty (23 AD).
Ban Gu (8 years and 32 years of Jianwu-4 years and 92 years of Yongyuan) was an official, historian and writer in the Eastern Han Dynasty. The son of Ban Biao, a historian, was born in Fufeng Anling (now the northeast of Xianyang, Shaanxi). In addition to the History of Lantai, he was transferred to the post of Secretary of Canon Studies and devoted himself to compiling Hanshu for more than 20 years.
Sima Qian wrote Historical Records, which ended in the early years of Emperor Wu of the Han Dynasty and was not recorded after the early years. Yang Xiong, Liu Xin, etc. Continue to compose music, but many of them are vulgar and distorted, which is not enough to follow historical books. Ban Biao angered the former history, and finally made sixty-five biographies. Because Ban Gu's previous history was not detailed, but subtle research, and he wanted to engage in his career, he followed his father's work, subtle research, continued his book, and followed his ancestors' career. Hanshu was written in the period of Emperor Wu of Han Dynasty, which lasted nearly forty years.
Hanshu created the historical records of China's chronicles in past dynasties, and laid a precedent for the revision of history. Historian Zhang Xuecheng once said in "The Meaning of Literature and History": "Shifting history is not a fixed law, but a 10% righteous example, so it is a lesson for future generations." In history, "the goodness of history, the first passage and solid", Banma also said that the two books have their own strengths, both of which are masterpieces of China history and must be read by those who study literature and history.
