Yan Zhiyi (颜之仪) (523–591), courtesy name Zisheng (子升),[1] was a native of Linyi County, Langya Commandery (琅琊郡) (now Shandong Province).
[4] In January 555, Western Wei (the precursor state of Northern Zhou) captured Jiangling, and Yan Zhiyi (presumably with his family) moved to Chang'an.
Yuwen Yun made errors during this expedition; while officials like Zheng Yi (郑译) were reprimanded for failing to correct the crown prince, Yan Zhiyi was rewarded for his repeated petitions.
[8] During the reign of Emperor Xuan, Yan Zhiyi was made a duke and his fiefdom increased to a thousand households.
[11] In 585, Yan Zhitui was made Inspector of Ji Prefecture (集州, in today Nanjiang County, Sichuan).
