Answer the following question: Information: - Jia Chong (217282), courtesy name Gonglu, was an official who lived in the late Three Kingdoms period and early Jin dynasty. He started his career as an advisor to Sima Shi and Sima Zhao, the regents of the state of Cao Wei in the Three Kingdoms era, and subsequently served as an official in the court of Sima Zhao's son, Sima Yan (Emperor Wu), after the establishment of the Jin dynasty. - Sima Zhao (211265), courtesy name Zishang, was a military general, politician and regent of the state of Cao Wei during the Three Kingdoms period of Chinese history - Emperor Hui of Jin (259 - January 8, 307), personal name Sima Zhong (), courtesy name Zhengdu (), was the second emperor of the Jin Dynasty (265-420). Emperor Hui was a developmentally disabled ruler, and throughout his reign, there was constant internecine fighting between regents, imperial princes (his uncles and cousins), and his wife Empress Jia Nanfeng for the right to control him (and therefore the imperial administration), causing great suffering for the people and greatly undermining the stability of the Jin regime, eventually leading to Wu Hu rebellions that led to Jin's loss of northern and central China and the establishment of the competing Sixteen Kingdoms. He was briefly deposed by his granduncle Sima Lun, who usurped the throne himself, in 301, but later that year was restored to the throne and continued to be the emperor until 307, when he was poisoned, likely by the regent Sima Yue. - The War of the Eight Princes, Rebellion of the Eight Kings or Rebellion of the Eight Princes was a series of civil wars among kings/princes (Chinese: "wang" ) of the Chinese Jin dynasty from AD 291 to 306. The key point of contention in these conflicts was the regency over the developmentally disabled Emperor Hui of Jin. The term stems from biographies of eight princes collected in chapter 59 of the "Book of Jin" ("Jinshu"). - Sima Shi (208 March 255), courtesy name Ziyuan, was a military general and regent of Cao Wei during the Three Kingdoms era of Chinese history. In 249, he assisted his father Sima Yi in overthrowing the emperor Cao Fang's regent Cao Shuang, allowing the Sima family to become paramount authority in the state, and he inherited his father's authority after his father's death in 251. He maintained a tight grip on the political scene and, when the emperor Cao Fang considered action against him in 254, he had Cao Fang deposed and replaced with his cousin Cao Mao. This tight grip eventually allowed him to, at the time of his death in 255, transition his power to his younger brother Sima Zhao, whose son Sima Yan eventually usurped the throne and established the Jin dynasty. - Cao Wei (220265) was one of the three major states that competed for supremacy over China in the Three Kingdoms period (220280). With its capital at Luoyang, the state was established by Cao Pi in 220, based upon the foundations laid by his father, Cao Cao, towards the end of the Eastern Han dynasty. The name "Wei" first became associated with Cao Cao when he was named the Duke of Wei by the Eastern Han government in 213, and became the name of the state when Cao Pi proclaimed himself emperor in 220. Historians often add the prefix "Cao" to distinguish it from other Chinese states known as "Wei", such as Wei of the Warring States period and Northern Wei of the Southern and Northern Dynasties. The authority of the ruling Cao family gradually weakened after the death of the second Wei emperor, Cao Rui, and eventually fell into the hands of Sima Yi, a Wei regent, and his family, in 249. Cao Rui's successors remained as puppet rulers under the control of the Simas until Sima Yi's grandson, Sima Yan, forced the last Wei ruler, Cao Huan, to abdicate the throne and established the Jin dynasty. - The Book of Jin is an official Chinese historical text covering the history of the Jin dynasty from 265 to 420. It was compiled in 648 by a number of officials commissioned by the imperial court of the Tang dynasty, with chancellor Fang Xuanling as the lead editor, drawing mostly from official documents left from earlier archives. A few essays in volumes 1, 3, 54 and 80 were composed by the Tang dynasty's Emperor Taizong himself. The contents of the "Book of Jin", however, included not only the history of the Jin dynasty, but also that of the Sixteen Kingdoms period, which was contemporaneous with the Eastern Jin dynasty. - Jia Nanfeng ( ) ( 257 -- 300 ) , nickname Shi ( ) , was the daughter of Jia Chong and first wife of Emperor Hui of the Jin Dynasty ( 265 -- 420 ) and also the granddaughter of Jia Kui . She is commonly seen as a villainous figure in Chinese history , as the person who provoked the War of the Eight Princes , leading to the Wu Hu rebellions and the Jin family 's loss of northern and central China . What is the relationship between 'jia nanfeng' and 'emperor hui of jin'?
