What is the origin of Qingzhou Army?

When Cao Cao arrived in Yanzhou, he was assisted by Coss, Cao Hong and Xiahou Chunfu, who were few in number and strong in strength. His influence in Yanzhou has developed rapidly. Cao Cao got a great counselor Xun. (Yu). Hey? Help Cao Cao advise: "Dong Zhuo's tyranny is extreme and he will surely die in turmoil." He suggested that Cao Cao concentrate on expanding in Yanzhou. Cao Cao accepted his suggestion.

At this time, the Yellow Scarf Army in Qingzhou has made great progress. They poured into Yanzhou from Qingzhou and killed Liu Dai, the secretariat of Yanzhou. The yellow turban insurrectionary army can only move and fight, but it doesn't know how to take Yanzhou as its base. After Liu Dai's death, Yanzhou was leaderless. The news reached Puyang, and Cao Cao, the satrap of the East County, sent Chen Gong, an adviser, to persuade Yanzhou officials. In this way, Cao Cao easily became a Yanzhou shepherd without a single soldier.

Cao Cao knew that the most important thing to dominate the Quartet was to have a strong military force. He sent troops to fight the Qingzhou Yellow Scarf Army and won several battles. When the Yellow Scarf Army encountered setbacks, he wrote a letter to Cao Cao. The letter said: "When you were in Jinan in the past, you destroyed more than 600 Baal temples and won the support of the people. You have to see that the fate of the Han Dynasty has been exhausted, and it is God's will that you can't save it. " Cao Cao saw from the letter of the Yellow Scarf Army that they had no fighting spirit and admired themselves. So he gave priority to military strikes, supplemented by induced surrender. Qingzhou Yellow Scarf Army lacked an effective commander, so it laid down its arms and surrendered. Cao Cao selected 300,000 young and middle-aged people from this peasant army and called it "Qingzhou Army". Since then, Qingzhou soldiers have become the backbone of Cao Jun.
