Therefore, Zhang Yan was granted the title of General of Pingzhonglang in an attempt to disintegrate the rebel army. When Cao Cao pacified Jizhou, Zhang Yan led his troops to surrender. The remaining tribes were also suppressed by Cao Cao and Yuan Shao before that. The Yellow Turban Uprising and the people's uprisings of all ethnic groups affected by it continued to carry out heroic struggles for more than 20 years from the first year of Zhongping under Emperor Ling to the middle period of Jian'an under Emperor Xian. The Yellow Turban Uprising went through long-term preparations in advance and was relatively well-organized. It publicly announced that it would overthrow the Eastern Han Dynasty and establish the peasants' own political power, which was a significant improvement over previous peasant uprisings. Due to the weakness of the revolting peasants themselves, they were brutally suppressed successively. However, under the heavy blow of the peasant uprising, the decadent Eastern Han Dynasty existed in name only.
