Li Guang, a descendant of the famed general Li Xin who captured Crown Prince Dan of Yan during the Qin Dynasty, came from a family of expert horsemen and archers. In the fourteenth year of Emperor Wen of Han's reign, he joined the army and distinguished himself against the Xiongnu with his exceptional riding and archery skills, earning the rank of Commandant of the Palace. He once accompanied Emperor Wen on an imperial tour, charging into battle with fearless valor and fighting wild beasts on the march with unmatched ferocity. Emperor Wen sighed regretfully, "What a pity you were born in the wrong era. Had you lived during Emperor Gaozu's founding days, a marquisate of ten thousand households would have been yours without question!"
After Emperor Jing of Han ascended the throne, the kingdoms of Wu and Chu rebelled. General Li Guang fought under Grand Commandant Zhou Yafu, distinguished himself by capturing enemy banners at Changyi, and was later appointed governor of Shanggu on the frontier. The Xiongnu were so aggressive that they engaged Li Guang in daily battles with multiple forces. A man named Gongsun Kunqiu, fearing for Li Guang's safety, tearfully told the emperor, "Li Guang's talent is unmatched in the world. But he relies on his skill and constantly fights the Xiongnu—I fear he will be killed!" So Emperor Jing transferred Li Guang to be governor of Shangjun.
Later, Li Guang served as governor of Longxi, Chengji, Yanmen, Daijun, and Yunzhong, earning fame for his fearless combat in each post. The Xiongnu called him the Flying General, fleeing from him as if avoiding a plague.
Later, the idiom "Unmatched Talent" came to describe someone whose ability and spirit are unrivaled in the world.
