General Li Guang was born in Longxi. Li Guang's family has been learning archery for generations. Because he is proficient in horseback riding and archery, he has gained a lot by killing the enemy and beheading. With Qiu Zhou Yafu counterattacking the rebels, he won the enemy's flag in Changyi City, made great contributions, and became famous in one fell swoop, and was famous for his ability to recruit good fighters. When the Huns invaded Shang Jun on a large scale, there were several dry cavalry. Li Guang's one hundred cavalry were also very alarmed and wanted to run back. Li Guang said; "We are dozens of miles away from the army, and now we have escaped with one hundred cavalry. As soon as the Huns catch up with the shooting, it's all over. If we stay now, the Huns must think that we are luring the enemy for the army and dare not attack us. " Li Guang ordered the cavalry to say, "Forward!" When he reached a place about two miles away from the Xiongnu, Xu stopped and ordered, "dismount and untie your saddle!" " "At this time, it was just dark, and the Xiongnu soldiers always felt very strange and dared not attack. At midnight, everyone was evacuated. Li Guang was guarding the right Beiping, and the Huns heard his name and called him "the flying general of the Han Dynasty". I've been hiding from him for years, and I'm afraid to go into right Beiping. Li Guang is very honest, and rewards are often given to subordinates, eating and drinking with foot soldiers. Li Guang died, and there was little money left at home. He never talks about family property. Li Guang is all thumbs and seldom talks. He played archery until his death. Li Guang led the troops, and wherever food and water were scarce, the foot soldiers didn't drink water, and he didn't go into the water. Not all the foot soldiers eat. He didn't eat. He is generous and not harsh, so the foot soldiers love him and are willing to contribute to him.
