Context_1 : Yuwen Tai () (507556), nickname Heita (), formally Duke Wen of Anding (), later further posthumously honored by Northern Zhou initially as Prince Wen () then as Emperor Wen () with the temple name Taizu (), was the paramount general of the Chinese/Xianbei state Western Wei, a branch successor state of Northern Wei. In 534, Emperor Xiaowu of Northern Wei, seeking to assert power independent of the paramount general Gao Huan, fled to Yuwen's domain, and when Gao subsequently proclaimed Emperor Xiaojing of Eastern Wei emperor, a split of Northern Wei was effected, and when Yuwen subsequently poisoned Emperor Xiaowu to death around the new year 535 and declared his cousin Yuan Baoju emperor (as Emperor Wen), the split was formalized, with the part under Gao's and Emperor Xiaojing's control known as Eastern Wei and the part under Yuwen's and Emperor Wen's control known as Western Wei. For the rest of his life, Yuwen endeavored to make Western Wei, then much weaker than its eastern counterpart, a strong state, and after his death, his son Yuwen Jue seized the throne from Emperor Gong of Western Wei, establishing Northern Zhou. Context_2 : The Southern Qi () (479-502) was the second of the Southern dynasties in China, followed by the Liang Dynasty. During its 23-year history, the dynasty was largely filled with instability, as after the death of the capable Emperor Gao and Emperor Wu, Emperor Wu's grandson Xiao Zhaoye was assassinated by Emperor Wu's intelligent but cruel and suspicious cousin Xiao Luan, who took over as Emperor Ming, and proceeded to carry out massive executions of Emperor Gao's and Emperor Wu's sons and grandsons, as well as officials that he suspected of plotting against him. The arbitrariness of these executions was exacerbated after Emperor Ming was succeeded by his son Xiao Baojuan, whose actions drew multiple rebellions, the last of which, by the general Xiao Yan led to Southern Qi's fall and succession by Xiao Yan's Liang Dynasty. Context_3 : Wei Zifu (Traditional Chinese: ; Simplified Chinese: ; pinyin: Wei Zifu) (died 91 BC), posthumously known as Empress Xiaowu Si () or Wei Si Hou (, "Wei the Thoughtful Empress"), was an empress during ancient China's Han Dynasty. She was the second wife of the famous Emperor Wu and his spouse of 49 years, and stayed as his empress for 38 years, the second longest in Chinese history (behind only the 42-year reign of Empress Wang, the wife of Ming Dynasty's Wanli Emperor, who came over 1,600 years later). She was the mother of Emperor Wu's heir apparent, Crown Prince Liu Ju, as well as the older half-sister of the famed general Wei Qing, the younger aunt of Huo Qubing, the step-aunt of Han statesman Huo Guang and the great-grandmother of Liu Bingyi.

He was Emperor Wu (Xiao Ze)'s oldest son, but predeceased his father. After his death, his son Xiao Zhaoye became crown prince and eventually succeeded Emperor Wu, but was soon thereafter overthrown by Emperor Wu's cousin Xiao Luan, who took over the throne. By 498, all of Xiao Zhangmao's descendants had been exterminated. Context_5 : Cao Cao ( ; ; 155 15 March 220), courtesy name Mengde, was a Chinese warlord and the penultimate Chancellor of the Eastern Han dynasty who rose to great power in the final years of the dynasty. As one of the central figures of the Three Kingdoms period, he laid the foundations for what was to become the state of Cao Wei and was posthumously honoured as "Emperor Wu of Wei". He is often portrayed as a cruel and merciless tyrant in subsequent literature; he has also been praised as a brilliant ruler and military genius who treated his subordinates like his family. During the fall of the Eastern Han dynasty, Cao Cao was able to secure the most populated and prosperous cities of the central plains and northern China. Cao had much success as the Han chancellor, but his handling of the Han emperor Liu Xie was heavily criticized and resulted in a continued and then escalated civil war. Opposition directly gathered around warlords Liu Bei and Sun Quan, whom Cao was unable to quell. Cao was also skilled in poetry and martial arts and wrote many war journals.

He was posthumously honored as crown prince after his father Emperor Zhongzong was restored to the throne in 705 and in 706, Emperor Zhongzong provided Li Chongrun with an honorable burial by interring his remains at the Qianling Mausoleum. Context_7 : Yuan Xie () (died 508), ne Tuoba Xie (, changed 496), courtesy name Yanhe (), formally Prince Wuxuan of Pengcheng (), later posthumously honored as Emperor Wenmu () with the temple name of Suzu (), was an imperial prince of the Chinese/Xianbei dynasty Northern Wei. He was a son of Emperor Xianwen, and he often assisted his brother Emperor Xiaowen both in military and governmental matters. After Emperor Xiaowen's death, he briefly served as regent for Emperor Xiaowen's son Emperor Xuanwu. Eventually, due to suspicions and jealousy of Emperor Xuanwu's uncle Gao Zhao, Emperor Xuanwu believed false reports that Yuan Xie was going to rebel, and forced him to commit suicide. He was later posthumously honored as an emperor by his son Emperor Xiaozhuang, although subsequently Emperor Jiemin retracted the honors. Context_8 : Mu Tipo () (died 577), ne Luo Tipo (), was an official of the Chinese dynasty Northern Qi. He was a close associate of the emperor Gao Wei, and during the latter part of Gao Wei's reign controlled the political scene along with his mother Lu Lingxuan, and the other favorites of Gao Wei, Han Zhangluan and Gao Anagong. In 577, in the midst of a major attack by rival Northern Zhou, Mu surrendered to Emperor Wu of Northern Zhou and was made a provincial governor, but after Northern Zhou destroyed Northern Qi and took over its territory, Emperor Wu falsely accused Mu of conspiring with Gao Wei, and killed Mu and forced Gao Wei and other members of the Gao clan to commit suicide.
