During the Northern Zhou Dynasty

After the death of Emperor Xuan, court officials led by Liu Fang (刘昉) and Zheng Yi (郑译) amended the edict containing Emperor Xuan's will, making Yang Jian (the later Emperor Wen of Sui) chancellor and chief counselor for the young Emperor Jing. Yan Zhiyi, knowing that this was not Emperor Xuan's true intentions, refused to join in the plot. Later, after Yang Jian had become chancellor and regent, he asked Yan Zhiyi for the Imperial Seal. Yan replied with a stern expression,"The Seal belongs to the Emperor; why is the Chancellor demanding to possess it?" Yang Jian was so angered by the reply that he ordered Yan to be dragged out and executed. However, remembering and apprehending Yan's excellent reputation with the people, Yang Jian halted the execution. During the Sui Dynasty
