Xu Guang (Later Zhao)

Xu Guang (fl. 4th century CE) was an official who served under the Later Zhao dynasty during the Sixteen Kingdoms period of Chinese history. Details regarding his life are scarce, but he is primarily known for his role in advising Shi Hu, the second emperor of Later Zhao.

Historical records indicate that Xu Guang held a position of considerable influence at court. He was involved in advising Shi Hu on matters of governance, including legal reforms and personnel selection. Accounts suggest he often cautioned Shi Hu against excessive cruelty and extravagance, although the extent of his influence in curbing the emperor's more tyrannical tendencies remains debated by historians.

Xu Guang is often mentioned in conjunction with other notable officials of the Later Zhao period, such as Zhang Bin and Wang Bo. He appears to have been part of a group of advisors who, to varying degrees, attempted to mitigate the negative impacts of Shi Hu's often brutal reign.

The exact dates of his birth and death, as well as his specific official titles, are not consistently recorded across historical sources, contributing to the limited information available about his life and career. While not a central figure in the broader narrative of the Sixteen Kingdoms, Xu Guang represents one of many officials who navigated the complex and often dangerous political landscape of the era.
