A native of Ji Cheng (now Qin 'an, Gansu), he was the grandson of Han Fei's general Li Guang. "Little Zhang Shijian prison. Good at riding and shooting, loving humility corporal, very famous "; Plus, after he became famous, he naturally won the favor of Hanwu for a long time. "I thought Shi Li would ride 800." Taste the Huns for more than 2,000 miles, live in Juyan depending on the terrain, and return without seeing anything. "Soon," worship for a captain riding a captain will brave five thousand people, teach them to shoot Jiuquan and Zhangye to prevent Hu ",subject to the incompetent and arrogant national Qi, General Li Guangli of the Second Division. In fact, the tragedy of Li Ling's life began from this moment and has been officially staged.

Li Guangli is a jealous and narrow-minded person, so he won't let Li Ling show off. "In the second year of Tianhan, the Second Division rode 30,000 out of Jiuquan and attacked the right king of Tianshan Mountain." With Li Ling's talent, he should have occupied an important position in the party and charged ahead; However, Li Guangli is going to put him in charge of logistics. Li Ling, who is devoted to serving the country and is not worldly, naturally doesn't want to, but kowtows to Hanwu and asks himself:' The people I want to send to the border are warriors and swordsmen in Jingchu, willing to be the first team, alone in the south of Ganlan Mountain, and don't have to be the second division of the township. "And set up the rhetoric of" willing to hit the public with less, and 5,000 infantry involved in the court ". Miss Li is naturally very unhappy. However, Hanwu, who was eager to use troops, deeply appreciated him, and led the crossbow captain Lu Bode to meet Li Ling's army in the middle of the road as a side response. Bode used to be a general in Fu Bo, but he didn't want to stay behind the mausoleum. He said, "Xiongnu horses in Fang Qiu are too fat to fight. I hope that from the tomb to the spring, I will take five thousand people to ride Jiuquan and Zhangye and attack things, but they will be captured. ".Hanwu" resented Ling's reluctance to go out and taught Bode to write letters ".He was furious and refused. Li Ling hurried to lead the troops with 5,000 troops, and the soldiers left behind.

In late October, Ling Jun arrived at Xunji Mountain and met thirty thousand cavalry of Khan. Seeing that the Han army was few, Xiongnu soldiers swarmed and besieged. "Ling war attack, thousands of crossbows, draw string falls. Lu also went up the mountain, and the Han army pursued and killed thousands of people. Khan was frightened and summoned about 80 thousand soldiers to attack the mausoleum on horseback. Ling fought and led, went south for a few days, and arrived in the valley laughing. Because of continuous fighting, most of Ling Jun's soldiers were injured, but their morale did not dare to slack off. Fight again tomorrow and cut more than 3 thousand people. Alone, but reinforcements have not yet arrived, and Li Ling is doomed to fight and retreat. "South to the foot of the mountain, khan in nanshan, make his son will ride strike ling. Ling Jun fought in the Woods and killed thousands of people. Khan fell because of a sniper's shot. "

In the face of such a powerful and fearless opponent, the Xiongnu army did not understand the reality of the Ling Jun army, thinking that it was facing the elite of the Han army; At this time, Li Lingjun had retreated to the frontier fortress not far from the Han Dynasty, and Khan was also worried that he would lead the enemy into the encirclement and annihilate, so he was timid and ready to retreat. Just then, a traitor named Guan Gan, a soldier in the Lingjun, surrendered to the Xiongnu because of the humiliation of the captain, and told him that "Lingjun had no way to save, and it was exhausted, and the general and Cheng' an Hou sent forward alone." Khan was overjoyed when he heard the news, but he made an urgent order to attack the Ling army. On the eighth day of Lien Chan, the Han army retreated. "If we don't reach Khan Mountain, 500,000 arrows will be consumed in one day. . . Not if the foot soldiers die too much. ""The Huns blocked the narrow road, and the tomb was short of food, so reinforcements couldn't come. "Soldiers trapped, horses and ammunition. Knowing that he had been calculated, Li Ling sighed, "It is enough to get rid of dozens of arrows. "Some military officials advised me to return to Taoism, but Li Ling refused. He said," I will not be a strong person until I die. " And ordered the soldiers to escape overnight, lest "there are things to report to the son of heaven. "In the middle of the night" drums are beating, but the drums don't ring. Ling and Han Yannian both mounted their horses, followed by more than ten strong men. "。 Lu rode thousands after him, and Han Yannian died. Ling said, "I have no face to report to your majesty!" " Surrender. "

Li Ling's defeat was mainly due to the delay in the arrival of Li Guangli's reinforcements. However, it is not a miracle that Li Ling resisted the Xiongnu's 80,000 brave enemies with 5,000 soldiers for nearly ten days. It's a pity that Li Ling failed to honor his promise that "I won't die, and I won't be a strong man", but died on the battlefield like Han Yannian, which was the beginning of his big mistake in life. Or is it because he is still young and wants to win reinforcements from two divisions in the future? Or does he want to hide his strength for the future? Of course, since ancient times, there has been no reason to win a war, and defeat is likely to be surrender. However, in any case, military commanders are afraid of death and surrender to the enemy. In modern America, they can still "surrender gloriously" and win understanding and even applause. In the popular slogan "Long live the traitor", it is a little boy who has no rules with the world, jumping around naked and screaming hysterically, and may also win the taste of mutual appreciation. However, in China's traditional ethical framework of "success or failure", it must not be allowed; In any society that respects the individual more than life and longs to realize personal value in the realization of personality, it is probably rarely allowed. And since ancient times, many brave people have been captured and persevered. Yue Fei said that "civil servants don't love money, and military officers are not afraid of death." Therefore, Li Ling's surrender cannot be justified in any case. This is where Li Ling was hated by later generations.
