The example of regional classification begins with Liu Xin's Seven Views. Ban Gu's Hanshu begins with Yiwenzhi, which is divided into six parts: Six Arts, hundred schools of thought, Poetry and Fu, Art of War, Numerology and Fangshu. Later, The Book of the New Tang Dynasty, The History of the Song Dynasty, The History of the Ming Dynasty and The Draft of the History of the Qing Dynasty also compiled Yiwenzhi one after another.
Historical Records is a catalogue of books recorded in China's ancient history books. For example, Sui Shu.
Sui Shu is the beginning of Jing Shi Zhi, and The Preface of Jing Shi Zhi says: "The Wei family took the place of Han, and died of mining. It was hidden in the three pavilions of ministers at home and abroad, and Minister Wei Lang started the classics." The History of Sui Shu's Classics is the first book that divides the classics into four parts: Classics, History, Zi and Ji, and is accompanied by two kinds of classics: Buddhism and Taoism. Until the Qing Dynasty, the Four Ku Quanshu still used four volumes. The achievement of Sui Shu Jing Ji Zhi is the first comprehensive summary of the development of historiography in Wei, Jin, Southern and Northern Dynasties.
