Yan Zhenqing's calligraphy achievements were provided by the author in the Palace Museum, which is comparable to Wang Xizhi. His "Manuscripts for Tribute to Nephews" is known as "the second running script in the world". This short and messy sacrifice is not only praised for its calligraphy, but more importantly, it is a heroic elegy. Today, the author tries to help readers better understand this famous calligraphy work from the perspective of historical materials and diction. The Manuscript of Tribute to Nephews, which was written by Yan Zhenqing in 758 to commemorate Yan Jiming, Yan Zhenqing's dead nephew, caused Fan Yang to become a soldier and committed Shun, recorded the heroic deeds of Yan's people in their heroic struggle and sacrifice during the An Shi Rebellion, which took place in 755. The Old Book of the Tang Dynasty, Biography of Yan Zhenqing: The signs of rebellion in Anlu Mountain are gradually obvious. Yan Zhenqing, the governor of the plain, built the city and dredged the pond for the reason that the rain broke the city wall, and secretly expanded the armaments and provisions. In November (755), the "An Shi Rebellion" broke out. Due to the lack of defense, all the Heshuo states fell within a month. The plain city guarded by Duyan Zhenqing did not fall. The rebels went south along the North China Plain, and there was no danger to defend all the way. They quickly moved westward and captured Luoyang, and their sword pointed at Chang'an. At that time, Yan Zhenqing urgently recruited warriors, and ten thousand people were recruited every ten days. Yan Zhenqing captured the enemy generals and cut the sacrificial flag at the waist; He also fought against Yan Gaoqing, the brother of the governor of Ren Changshan (now Shijiazhuang, Hebei Province), and Yan Jiming, the son of Gao Qing, was the messenger. The Manuscript records: "The bandits are free to challenge, and the soldiers are obedient. My father is dedicated. He is a county in Changshan. He is also on the plain when he is ordered. My brother loves me, and Bale is rumored." Yan Gaoqing was outnumbered. He had no choice but to feign surrender to the rebels. He set up a plan to divert the tiger from the mountain, capture and kill the rebels, and demobilize the rebels. Jingxing Pass was recovered. After hearing the news, the Hebei prefectures that had surrendered to the enemy killed their bogus officials again. All the seventeen prefectures belonged to the imperial court. The army combined more than 200000 troops. They defeated Yan Zhao and jointly promoted Zhen Qing as the leader of the alliance. "Manuscript" records: "Since you have come to the end, you should open the earth gate." The Manuscript for Tribute to Uncle and the Manuscript for Tribute to Nephew were written in the same year. Yan Zhenqing told his uncle on the way of demotion, and the things he told were similar to the Manuscript for Tribute to Nephew: "(Gao Qing) was loyal and courageous. He opened the earth gate first, captured and cut the enemy's back, and defeated his villainy." The channel between the rebel front in Luoyang and Fan Yang in the rear was cut off, causing Anlushan to gather a large number of elite troops to fight back. Yan brothers won precious time for the imperial court to move westward to preserve its strength and mobilize the army to counter rebellion! The rebels who surrounded the isolated city and fought back in full force are threatening. The rebels stormed Hebei, and the prefectures were successively sunk. In a critical situation, Yan Gaoqing sent Yan Quanming, another son, and Zhang Tongyou, his subordinate, to ask for help from Wang Chengye, the governor of Taiyuan. Zhang Tongyou's family was killed in An Shi Rebellion. When Yan Gaoqing sent Yan Quanming to the imperial court for help, Zhang Tongyou begged for revenge. However, Zhang Tongyou felt that the Taiyuan austerity envoy Wang Chengye could turn to him after he arrived in Taiyuan, so he came up with the ghost idea of selling the owner for glory and taking revenge: he suggested that Wang Chengye detain Quan Ming and others, change all the musical instruments they brought to the court, and let Wang Chengye take the credit for recovering the Tumen. It is suggested that Wang Chengye should support the troops and not save them. When the time comes, there will be no proof of death, so that he can take the credit of the king. therefore
