For example, the works of Xin Qiji and Wang Anshi in history are far from limited to their literary works. The same is true of Yan Zhenqing, who once commanded 200,000 troops to pacify the war. According to the Book of Old Tang Dynasty, Yan Zhenqing offended Yang all the way in the imperial court and was transferred from Beijing. But it was this callback that made Yan Zhenqing leave every dark cloud with a ray of hope and created his own historic achievements. At that time, Yan Zhenqing was transferred from Pingyuan County, which was under the jurisdiction of An Lushan.
However, after Yan Zhenqing came to power, he realized very early that Anmushan had the intention of rebellion, so he began to build private cities and hoard food. Finally in Tianbao 14, An Lushan really rebelled. Other cities have fallen. But only the city of Yan Zhenqing can be immune. Only 33 days after the rebellion, An Lushan attacked Luoyang. At this time, Yan Zhenqing was appointed commander-in-chief of the allied forces, and the commander-in-chief of 200,000 troops began to quell the rebellion. Yan Zhenqing led twenty warriors across Zhao Yan. As a result, An Lushan rebels could not attack Tongguan quickly. ? It is precisely because of the pacification of this war. Yan Zhenqing was not only transferred back to Beijing. Moreover, he was awarded the position of minister of punishments, and was later promoted to an ancient bachelor.
