Did Li Ling really surrender?

Emperor Wu of the Han Dynasty was moody, headstrong and crony. A few days ago, when Li Ling marched on the water in Longle, he drew a map of the mountains and rivers that passed by and sent someone to report to the court. Emperor Wu was very happy and made a wish to be an official. The princes and ministers all raised their glasses to congratulate him. Now that I have heard the news of Li Ling's surrender, I am unhappy and unhappy. The minister is worried and doesn't know what to do. Originally, Emperor Wu wanted to take this opportunity to promote Li Guangli, but Li Guangli failed to make achievements. A surname asked Sima Qian to defend Li Ling, but Emperor Wu thought he was a lobbyist for Li Ling, deliberately slandering and belittling Li Guangli. This caused the jealousy of Emperor Wu, and Sima Qian was punished for corruption. So full of Wu Wen, silenced. After a long time, Emperor Wu realized that there was no one to help Li Ling when he was defeated, so he sent messengers to express condolences to Li Ling's men who fled back. The following year, Emperor Wu got the false accusation that Li Ling instigated Khan to prepare for the war against Han, so he slaughtered Li Ling's mother, brother and wife. Khan took his wife as his concubine and cut off Li Ling's desire to return to Han. Later, Su Wu, the corps commander, sent a special envoy to Xiongnu because of something. Khan was frightened of everything and ordered Li Ling to persuade him in many ways. Su Wu stood upright, unmoved. Li Ling sighed and said, "Woo! My sin has gone to heaven! " Later, the Han Dynasty reconciled with the Huns, and Su Wu was released back to China. Li Ling buys wine to entertain Su Wu and dances and composes music. The truth was touching and tears fell down.
