隋书
The Book of Sui (Suí Shū) is the official history of the Sui dynasty. It ranks among the official Twenty-Four Histories of imperial China. It was written by Yan Shigu, Kong Yingda, and Zhangsun Wuji, with Wei Zheng as the lead author. In the third year of Zhenguan of the Tang dynasty (629), Emperor Taizong of Tang ordered Fang Xuanling to supervise the completion of the Book of Sui, which was being compiled around the same time as other official histories were being written. The Book of Sui was completed in 636 AD, the same year as the Book of Chen was completed.
