Later in the year, Shi Zun was overthrown by his adoptive nephew Shi Min, who supported another son of Shi Hu, Shi Jian the Prince of Yiyang, as the new emperor. As the turmoil continued, the Di and Qiang that Shi Hu had previously forced to move to eastern China began to disregard Later Zhao laws and seek to return to their ancestral homes in the west. They supported Pu Hong as their leader. In 350, when after Shi Min had issued an order for the slaughter of the non-Han, but particularly the Jie and the Xiongnu and began to show intent to take over the empire, Pu Hong was one of the generals resisting Shi Min. Later in the year, Jin created him the Duke of Guangchuan, and created Pu Jiàn the Duke of Xiangguo. However, Pu Hong did not hold on to the Jin-created titles for long, and soon declared himself the Prince of Sanqin (i.e., the prince of the Three Qins) and the Grand Chanyu, and changed his family name from Pu to Fu, in response to a prophecy. He intended to march west to occupy the Guanzhong region; however, as he was planning, he was poisoned to death by his general Ma Qiu; on his death bed, Fu Hong ordered Fu Jian to take over the Guanzhong region. Fu Jian, as his father's heir apparent, took over his troops and put Ma to death. He discarded the titles that his father had claimed, and again claimed the Jin-created titles.
