Huo Guang was the half-brother of Huo Qubing, a famed general of the Western Han Dynasty. After defeating the Xiongnu, Huo Qubing returned home and brought Huo Guang back to the capital Chang'an, where Emperor Wu appointed Huo Guang as a court gentleman.
Huo Guang was known for his meticulous and cautious nature. Before every court session, he would stand on the exact same small patch of ground outside the palace hall, never straying even a single inch beyond it. Over his 28 years serving Emperor Wu, he never made a single mistake, earning the emperor's deep trust.
On his deathbed, Emperor Wu appointed Huo Guang as Grand Marshal and General-in-Chief, tasking him with assisting the eight-year-old Emperor Zhao alongside Sang Hongyang. After Emperor Zhao's death, Huo Guang installed Liu He, Prince of Changyi, as emperor, only to replace him shortly after with Liu Xun, who became Emperor Xuan.
Thus, Huo Guang held both military and political power, becoming the most influential figure in and out of the imperial court. He governed for twenty years, implementing policies that eased the people's burdens and fostered social and economic development.
Although Huo Guang made contributions to preserving the Liu dynasty, he was unlearned and unskilled, lacking true understanding. Proud of his achievements, he monopolized all power. Officials with state matters had to first report to Huo Guang before they could present them to the emperor. At court sessions, even the emperor had to show him great deference. This bred resentment against Huo Guang among many.
Shortly after Emperor Xuan of Han ascended the throne, Huo Guang's wife plotted to marry their youngest daughter to the emperor as empress, but Xuan had already appointed Lady Xu as empress. Furious, Huo Guang's wife bribed the female physician Chunyu Yan to poison the pregnant empress just before childbirth. When the crime was exposed, Huo Guang not only covered for his wife but also interceded for Chunyu Yan, ensuring she escaped trial and imprisonment.
Because Huo Guang was ignorant and unlearned, lacking true understanding of righteousness and far-sighted strategy, within just three years of his death, his entire clan was wiped out, with all nine generations implicated and executed.
The idiom "no learning, no skill" originally referred to not reading or studying and having no good methods. Now it describes someone who has neither knowledge nor ability.
