The Anshi Rebellion is a major political event in Chinese history. It occurred in the 755 years of the Tang Dynasty. It started with the rebellion led by the prime minister of the Tang Dynasty and the deputy Xiang Shi Siming. Only the end. In contrast, Anlu Mountain's rebellion lasted only for 3 years, including differences in character influence, resources and war technology, and political and social backgrounds.

First of all, the reputation and influence of the rebels in the Anshi Rebellion Gao Lishi, the father of Shi Shi, and others far exceeded Anlushan and Shi Siming, and they could get more support and trust. The rebels in the Anshi Rebellion controlled large areas, including important cities such as Luoyang and Changan, making it difficult for the Tang Dynasty government to quickly calm the situation. In contrast, after the rebellion of Anlu Mountain, the government of the Tang Dynasty quickly launched a crackdown, forcing the rebels to retreat to the Hebei region, so the rebellion of Anlushan was shorter.

Secondly, the rebels in the Anshi Rebellion are larger and organized than An Lushan's rebels. They have more resources and advanced war technology. For example, they use new weapons such as gunpowder, thunderbolt, as well as military equipment such as war elephants. These advanced weapons and tactics brought the advantages of war to the rebels, making it difficult for the Tang Dynasty government to quickly calm the situation. In contrast, the scale of the rebels in Anlushan's rebellion was small, and the weapons and tactics did not bring enough advantages.

In the end, when the Anshi chaos occurred, the Tang Dynasty had entered the decline period, and the problems of political corruption and social turmoil were serious. Coupled with the main rebels in the Anshi Rebellion Gao Lishi and the father of Da Shi, they caught the dissatisfaction and opposition of the people. It was supported by a large number of people. In contrast, when the rebellion of Anlushan occurred, the Tang government was relatively stable, and the people's rebellion was not obvious. This also provides a certain support for the duration of the Anshi Rebellion.

In addition to the above reasons, there are other factors that have also affected the duration of the Anshi Rebellion. For example, the Tang Dynasty's political system, military management, and fiscal economy had serious problems, which caused the Tang Dynasty government to be unable to deal with the rebellion. In addition, the various ethnic and religious contradictions in the Tang Dynasty also made the rebellion forces more support, further exacerbating the dilemma of the Tang Dynasty government.

In addition, the length of the Anshi Rebellion is also affected by the international and regional environment. At that time, some countries and regions around the Tang Dynasty also faced political turmoil and military conflicts, which exacerbated the duration of the Anshi Rebellion. For example, during the outbreak of the Anshi Rebellion, Tibetan and Huizheng people in the surrounding areas also intervened in it, supporting the rebels, and further exacerbated the dilemma of the Tang Dynasty government. In addition, while the Anshi chaos occurs, some countries and regions around China have also occurred in some political turbulence and military conflicts. For example, the war between Turkic, Hui, Tubo and other countries has further affected the length of time of the Anshi chaos.

In short, An Lushan died for a year, but the Anshi Rebellion lasted for eight years because the reason was complicated. In addition to the differences in character influence, resources and war technology, political and social background, it is also affected by various factors such as international and regional environment. This rebellion not only caused great damage to the Tang Dynasty government, but also had a profound impact on Chinese history and culture. It was hailed as one of the major events in ancient Chinese history.
