What kind of country was Cao Cao’s Northern Expedition to Wuhuan? Why are their descendants not seen?

The reason is that Cao Cao completely wiped them out. After Wuhuan destroyed the country, Cao Cao took away 10,000 cavalry and tens of thousands of residents. Some people evaded pursuit in order to restore the country, but they were captured by the powerful Xianbei people. annexation. After that, the descendants of Wuhuan disappeared completely. Cao Cao moved the Wuhuan people into the interior, so that they could be assimilated by the Han people and completely changed their minds. Wuhuan is a country surrounded by mountains and rivers. The local residents have special customs. During the Han Dynasty, after Emperor Wu of the Han Dynasty drove away the Xiongnu, Wuhuan was able to establish a country. As time went by, in the Three Kingdoms period, because Tadun, the leader of Wuhuan, took in Yuan Shao's descendants, Cao Cao wiped out Wuhuan in a fit of anger. After that, Cao Cao pacified the north and made the people live and work in peace and contentment. The Wuhuan people also integrated into the life of the Han people.

After the Battle of Guandu, Cao Cao defeated the powerful enemy Yuan Shao in the north with less, and most of the Central Plains was in Cao Cao's hands. At this time, Yuan Shao's eldest son and second son are still fighting against Cao Cao. They control Youzhou and have a good relationship with Wuhuan. With the help of Wuhuan, Yuan Shang still failed to resist Cao Cao's attack. After the fall of Youzhou, Wuhuan's leader Tadun took Yuan Shang into custody. Cao Cao knew that Wuhuan was not a simple enemy, but under Guo Jia's persuasion, Cao Cao led an army to attack Wuhuan. After several months, he reached Wuhuan's territory. Finally, under Cao Cao's fierce attack, Wuhuan was defeated. Huan camp was captured, and Wuhuan leader Tadun was beheaded. The North was reunited. After Wuhuan destroyed the country, most of the local people were brought back to the Central Plains by Cao Cao, and the local cavalry and some strategic weapons were taken back by Cao Cao. Some Wuhuan descendants were annexed by the Xianbei people. After that, Wuhuan was destroyed and their descendants disappeared.

After the Wuhuan people moved into the interior, some of them changed their original surnames and adopted Han names, including Liu, Lu, Wang and other surnames. After decades of assimilation, the Wuhuan people still became Central Plains people. They began to accept the Central Plains culture and completely forgot the Wuhuan customs.
