Origin Story
东汉时期，著名史学家班固潜心研究历史，他博览群书，搜集了大量的史料，经过多年的努力，终于完成了他的巨著《汉书》。《汉书》不仅记述了西汉王朝从汉高祖刘邦到王莽篡汉的历史，而且对西汉的历史发展规律进行了深入的探讨，提出了许多独到的见解，形成了自己的一家之论。班固的《汉书》在史学界产生了深远的影响，被后人誉为“千古奇书”。班固的治学精神和《汉书》中的许多观点，直到今天仍然受到人们的推崇。
During the Eastern Han Dynasty, the famous historian Ban Gu devoted himself to the study of history. He read widely, collected a large amount of historical materials, and after years of hard work, finally completed his monumental work, "Book of Han". The Book of Han not only recounts the history of the Western Han Dynasty from Emperor Gaozu Liu Bang to Wang Mang's usurpation, but also conducts in-depth discussions on the laws of historical development of the Western Han Dynasty, presenting many unique insights that formed his own unique theory. Ban Gu's Book of Han had a profound impact on the historiography and was praised by later generations as a "marvelous book". Ban Gu's scholarly spirit and many of the viewpoints in his Book of Han are still admired today.
