During the Three Kingdoms period, there were many incidents of internal strife and rebellion in Eastern Wu, especially in the later period, among which the major generals who defected or defected were Han Dang's son Han Chun, Quan Qi's son Quan Qi, Bu Qi's son Bu Yi, etc. The clan rebelled or defected, there were Sun Fu, Sun Xiu, Sun Yi and other people, and today I will first talk about the three internal strife in the Eastern Wu Clan: Sun Quan's cousin was imprisoned, his nephew defected to Cao Wei, and his nephew defected to the Western Jin Dynasty.

Sun Fu
Sun Jian is a native of Fuchun, Wu County, Yangzhou, Sun Clan has been an official in Wudi for generations, the Chronicle of the Three Kingdoms says that Sun Jian "gai Sun Wu Hou also", from the perspective of Sun Jian's youth as a county official, Sun Clan should be a local noble family, so Sun Clan is prosperous, and sun Jian's peers are many, which also makes the number of clans after the founding of Eastern Wu a large number.
Sun Fu was the second son of Sun Jian's eldest brother Sun Qiang, and from a generational point of view, he was a cousin of Sun Ce and Sun Quan, Sun Ce made a lot of contributions when he was pacifying Jiangdong, and served as the Taishou of Luling, and after Sun Quan took charge of Jiangdong, Sun Fu took Sun Fu as the general of Pingnan and concurrently served as the assassin of Jiaozhou, becoming a major member of the party that held military power, which also provided certain conditions for him to have different intentions.
Sun Fu secretly communicated with Cao Cao on the grounds that Sun Quan was still too young to keep Jiangdong, and after being denounced, Sun Quan imprisoned him to death, but Sun Quan was not only good to his sons, not only did not add to them but also let them out.
Sun Yi
Sun Yi's father, Sun Yi, was the fourth son of Sun Jian's younger brother Sun Jing, and Sun Yi was Sun Yi's son- and grandson, who was also sun Ce and Sun Quan's nephew in terms of generations, sun Yi died in 234, and was posthumously promoted to the general of Yangwei and the Marquis of Fengshaxian, and after his death, he was inherited from the title by his concubine Sun Zi and continued to lead the army as a general of Zhaowu Zhonglang.
In the sixth year of Chiwu (243), Sun Cheng died, because he had no heirs, so the title was inherited by his brother-in-law Sun Yi, sun Liang, who was only ten years old after Sun Quan's death, ascended the throne, and the powerful minister Zhuge Ke controlled the government, and after Sun Jun killed Zhuge Ke, Sun Yi had meritorious service from the general of Zhennan to the general of the Zhen army, and the false governor Xia Kou held a military power.
After Sun Jun's death, he had exclusive power from his younger brother Sun Yi, and in 256, after killing Teng Yin and Lü Zhao, because both of them were Sun Yi's brother-in-law, Sun Yi sent Zhu Yi to attack Sun Yi for the ultimate trouble, so Sun Yi led his relatives and more than a thousand people to simply surrender to Cao Wei, and Sima Zhao was quite good to Sun Yi (Sima Yi and Sima Shi were dead at the time), and made him the General of CheQi, Yi Tongsansi, and the Marquis of Wu.
Sun Xiu
Sun Xiu's father was Sun Tai, a lieutenant of Changshui School, and Sun Tai's father was Sun Jian's fourth son, Sun Ce and Sun Quan's younger brother Sun Kuang, that is to say, Sun Xiu was Sun Quan's nephew, and sun Xiu and Cao Wei had a deeper relationship, because after Sun Ce pacified Jiangdong, Cao Cao married Cao Ren's daughter to Sun Ce's younger brother Sun Kuang in order to win Sun Ce and Sun Clan to marry him, and Sun Xiu had the blood of Cao Clan.
Sun Xiu served as a former general during the period of The Late Wu Emperor Sun Hao, and caused Sun Hao to be the overseer of Xiakou, which caused Sun Hao to be uneasy and jealous, and with Sun Hao's tyrannical personality, he would sooner or later attack Sun Xiu; in 270, Sun Hao sent his cronies He Ding to lead 5,000 troops to hunt in Xiakou, which caused Sun Xiu to fear and uneasiness, so he took his family and hundreds of relatives to the Western Jin Dynasty overnight (at this time, Cao Wei had already fallen to the country, and Sima Yan had already claimed the title of emperor).
Although there was a lot of criticism about Sima Shi's seizure of power and usurpation of the throne, he treated the kings of the fallen country and the heavy subjects and clansmen who surrendered to the enemy countries, such as Liu Chan and Cao Yan, and so did Sun Xiu, Who made Sun Xiu a general of the Hussars, Jiaozhou Mu, and Kaifu Yi Tongsan, and gave him the title of Duke of Hui, and the treatment was much higher than that of Sun Hao, who surrendered more than ten years later and was given the title of Marquis of Gui.
