Emperor Ming of the Tang Dynasty

During the fourteenth year of Tianbao, undercurrents surged in the seemingly prosperous Tang Empire. Emperor Xuanzong of the Tang Dynasty, Li Longji, was addicted to the opera garden and neglected government affairs, but he did not know that An Lushan had been working hard in Fan Yang for ten years, plotting a rebellion in the name of "worrying about the country and seeking rape"; Yang Guozhong controlled water transportation and imperial examinations, and used nepotism to make money, and poor students died unjustly; although Yang Guifei was favored by the emperor, she was keenly aware of An Lushan's ambitions, and secretly conveyed news but was often suspected. An Lushan sent his troops southward on the grounds of "Qingjun's side", and the 200,000 rebels were overwhelming. After the fall of Tongguan, Li Longji and Yang Guifei fled westward in haste, but encountered a mutiny by the Forbidden Army in Maweipo. After Yang Guozhong was executed, the soldiers still demanded that the "beautiful woman who brought harm to the country" be executed. Li Longji made a painful choice between the country and his true love, and finally killed Yang Guifei. Behind this coup, not only was the secret carve-up agreement between An Lushan and Yang Guozhong hidden in their early years, but it also exposed the fatal disease of the collapse of the prosperous dynasty system. Many years later, the secret letter planted by Gao Lishi before his death will eventually reveal the truth of this catastrophe.
