清代著名史学家赵翼,长期流览廿四史,写成《廿二史劄记》一书,成为后人研读廿四史的指示途经之作。为什么书的内容涉及廿四史,却以廿二史命名,历来介绍古代史籍的著作有不同解释。第一种解释,也是有关著作中最流行的一种解释是:“以乾隆初《明史》修成论刻廿二史之时,《旧店书》、《旧五代史》尚未定为正史,乃因明人所称‘廿一史’之习惯,另加《明史》,故名。” Zhao Yi, a famous historian in the Qing Dynasty, made long-term visits to the Twenty-Four Histories and wrote the “Twenty-two Historical Notes”, which became the guiding principle for later generations to study Twenty-Four Histories. Why the book covers the twenty-four history, but named after twenty-two history, the history of ancient books have always introduced different interpretations. The first explanation is also the most popular explanation of the writings: “When Qianlong first” Ming Dynasty “was revised into” 20th century history “,” Old Book “and” The Five Dynasties History of the Five Dynasties "have not been defined as the official history Due to Ming people called ’twenty-one history’ of the habit, plus ’Ming Dynasty’, hence the name.
