About “Book of Qi”
The Book of Qi, also known as the Book of Southern Qi, is a historical record of the Southern Qi dynasty, covering the years 479 to 502. It is one of the Twenty-Four Histories, a series of official Chinese historical texts. The book was written by Xiao Zixian during the Liang Dynasty, which followed the Southern Qi. Xiao Zixian was a member of the Southern Qi ruling family, being the grandson of Emperor Gao, the dynasty's founder. This makes the Book of Qi unique among the Twenty-Four Histories, as it was the only one written by someone from the dynasty it documents. (Summary adapted from Wikipedia, CC BY-SA 4.0.)
