Yongjia Rebellion

Due to the oppression of the Hu people and the indulgence of the gentry, this led to the tragic end of the Sima royal family, with the descendants of Sima Yi almost being completely slaughtered, Sima 48 Wang dying in Ningping, and it also resulted in the near annihilation of the descendants of the surrendered A Dou, ultimately leading to far-reaching impacts such as the 'Five Hu Chaos in China' and 'Clothing and Hats Moving South'. What historical event is this? Hint: Yongjia Rebellion, An Lushan Rebellion, Jingkang Incident.
