In BC 100, Su Wu and his party 100 arrived in Xiongnu, returned the Xiongnu emissary detained by the Han Dynasty, and presented gifts. Originally, Su Wu could return to China as long as he waited for the reply from Hun Khan, but a great event happened at this time.
When Su Wu and his party arrived in Xiongnu, Yu Chang, a subordinate of Xiongnu Wang Weifa, was plotting to kidnap Khan's mother and fled to the Han Dynasty. It happened that Yu Chang had a great friendship with Zhang Shengyou, the messenger of Su Wu in the Han Dynasty, and Yu Chang participated in this conspiracy with John Zhang. Who knows that just as they were preparing to launch a rebellion, someone told them the secret, Gou Jian and others were killed, and Yu was often captured alive. Originally, it had nothing to do with Su Wu, but the danger of being caught often made John Zhang give up. Khan was so angry that he wanted to kill the envoy of the Han Dynasty. Ministers advised him not to hand over Ambassador China, so Khan asked Wei Law to handle the matter.
When Wei Fa saw Su Wu, he told him to surrender. Su Wu flew into a rage and said, "I am an envoy of the Han Dynasty. If I disgrace my mission, how can I return to China alive! " Then he pulled out his sabre and rubbed it around his neck. Wei Lv was frightened and quickly hugged Su Wu, but Su Wu was seriously injured. After being rescued by the doctor, his life was finally saved. When Khan knew this, he also appreciated that Su Wu was a hero and wanted to have him.
After Su Wu recovered, Khan asked Wei Law to interrogate Yu Chang and others again. Wei Law killed Yu Chang in front of Su Wu, and then tried to kill John Zhang on charges of murdering Khan's recent minister. John Zhang, who was afraid of death, immediately knelt on the ground and expressed his willingness to go to the Huns. Wei Lu turned his head and said to Su Wu, "The deputy ambassador is guilty, so even the ambassador should sit together!" Su Wu said, "I am not related to John Zhang by blood. I know nothing about what he did. Why sit together? " Lv Wei once again raised his sword at Su Wu. Su Wu noodles don't change color. With ease and grace. Seeing that Su Wu was not frightened, he put away his sword and changed his smiling face. He said to Su Wu, "Mr. Su, I was forced to betray the Han Dynasty in those days, but I owed more to Corporal Lixian and gave me a title, which made me have tens of thousands of people, cattle and sheep all over the mountain, so rich. As long as you surrender, you can be like me at once. Why let yourself die in vain on this grassland? " Su Wu ignored him. Wei Law went on to say, "As long as you surrender, we are brothers. If you miss this opportunity, you will never see me again! " Hearing this, Su Wu had enough. He snapped, "Wei Law, you are the son of the Han people, and you are the minister of the Han Dynasty. You didn't want to be loyal to your country, but you betrayed your country and relatives, surrendered to the Huns, and became Khan's running dog. I know you just want to sow dissension between China and Hungary, and then do nothing. I, Su Wu, now that I know your intentions, how can I surrender to you as a traitor! "
When Wei Law learned that Su Wu refused to surrender, he reported to Khan, who admired Su Wu even more. In order to force him to surrender, Khan imprisoned Su Wu in a big cellar and cut off the food supply. It snowed heavily and there was no food, so Su Wu mixed the snow with the sheepskin on his clothes and ate it. A few days later, Su Wu survived. This made the Huns feel amazing, so they took Su Wu to a deserted place in Beihai (now Lake Baikal in Siberia, Russia) and asked him to graze the ram, saying that he would not release Su Wu until the ram gave birth to a lamb.
Year after year, Su Wu had a hard time in this bitter and cold place. No food was common, so Su Wu dug grass roots in the rat hole to eat. Although hard to this extent, Su Wu always took the Hanjie given to him by Emperor Wu of the Han Dynasty and never forgot his identity as an envoy of the Han Dynasty.
Many years have passed, and on this day, an old friend came to Beihai. At first glance, Su Wu is his good friend-Li Ling. At this time, Li Ling had surrendered to the Huns and was named King of Right School. Li Ling hosted a banquet in honor of Su Wu. During the dinner, Li Ling said to Su Wu, "In the second year of your mission, the holy family went to war against the Huns. I led 5000 soldiers as forwards. It's a pity that I went deep alone and was surrounded by tens of thousands of Xiongnu troops. I was defeated and captured. I wanted to have a chance to serve my country again. Who knows that the holy family killed my family indiscriminately, so I had to really surrender to the Huns. Now the emperor is old and moody, and dozens of ministers have been killed because of innocence. Your brother was forced to commit suicide because he was too young. Your old mother has passed away and your wife has remarried. As for your children, there is no news at all now! Brother Su, if life is fleeting, why bother yourself? "
Su Wu said to Li Ling, "My father and son have no merit in Sue's family. It was the emperor who made us leaders and made us among the leaders. We vowed to serve our country for a long time, even if our minds were full of brains! Now I can serve my country with my death in Su Wu, which is exactly what I want. You don't have to say anything more! If you have to force me to surrender, just consider me dead! " Seeing that Su Wu was so determined, Li Ling looked up at the sky and sighed, "What a strong son, a true righteous man. Wei Law and I are really treason!" After that, I couldn't help crying like rain, even my clothes were wet. After the banquet, Li and Sue shed tears respectively.
A few years later, Li Ling came to Beihai to tell the news of the death of Emperor Wu of the Han Dynasty in Su Wu. After hearing this, Su Wu issued the first cry in the direction of the Han Dynasty in the south, muttering to himself: "Your Majesty, Su Wu failed to repay your great kindness and serve the country wholeheartedly!" For months, Su Wu cried until he vomited blood.
In 8 1 year BC, Zhao Han, who ascended the throne, kissed the Huns again. The Han Dynasty asked the Huns about Su Wu, and the Huns lied that Su Wu was dead. Later, the mission of the Han Dynasty came to Xiongnu. It turned out that Su Wu's subordinate Chang Hui had someone report the news that Su Wu was still alive to Ambassador China. When meeting Hun Shan Yu, the clever Ambassador China said, "Your Majesty, my great man shot down a wild goose in Shanglinyuan. There is a silk book tied to the goose's foot, which says that Su Wu is now in Beihai. How can you say he is dead? " Hearing this, Khan had to put Su Wu and other nine people back into the Han Dynasty.
From BC 100 to BC 8 1 year, Su Wu was detained by Xiongnu 19. At the time of his mission, Su Wu was still in his prime, just 40 years old. When he returned to the Han Dynasty, he was nearly sixty years old and his hair and beard were all white. Even so, when he returned to Chang 'an, he didn't forget to take the Han Festival with him. People on both sides of the road greeted him and praised him as a real gentleman!
