As the ruler of Former Qin, Fu Jian appeared to be a diligent and thrifty ruler, and he abolished many of the harsh Later Zhao laws and invited able people to join his administration, but he was also violent and easily offended. For example, later in 351, he became increasingly angry that Jia had initially only suggested that he claim a princely title and not an imperial title, and he falsely accused Jia of conspiring with Jin's general Sima Xun and put Jia and his sons to death.
