Li Longji and Big Brother

Li Longji had a very good relationship with his elder brother, Li Xian. When Li Longji wrote letters to Li Xian, he addressed himself as " Brother Longji ", expressing his respect and closeness to his elder brother. Li Longji even conferred Li Xian the title of " Emperor Rang " to express his feelings for his brother. Li Xian was also very concerned about Li Longji. When he was sick, Xuanzong ordered the imperial doctor to treat him. On his birthday, Xuanzong personally came to congratulate him. After Li Xian's death, Xuanzong could not help but cry loudly and praise Li Xian's filial piety and benevolence. The relationship between the brothers was hailed as the model of royal brothers in later generations.

Li Longji's elder brother was Li Chengqi.

Li Longji (September 8, 685-May 3, 762) was the seventh emperor of the Tang Dynasty, the grandson of Emperor Gaozong Li Zhi and Emperor Wu Zetian, and the third son of Emperor Ruizong Li Dan. His reign lasted the longest, from September 8, 712 to August 12, 756. Li Longji was wise, decisive, versatile, and good at music and calligraphy. He created the three years of Xiantian, Kaiyuan, and Tianbao, and carried out the reform of the military system, the establishment of military governors, the trust of eunuchs, and the confinement of kings. He established a ruling system with eunuchs as the core. However, in his later years, he doted on Yang Guifei and neglected the government. In addition, he made policy mistakes and put important officials such as An Lushan in important positions, which led to the outbreak of the An Lushan Rebellion and laid the foreshadowing for the decline of the Tang Dynasty. He died at the age of 78 and was buried in Tailing. Li Longji was also a writer and had left behind many works of poetry.

Li Longji and Princess Taiping were aunt and nephew. Li Longji was the third child of Princess Taiping's brother, Prince Xiang Li Dan, so Princess Taiping was Li Longji's aunt. They launched a palace coup together during Tang Long's coup. Li Longji successfully seized power, and Princess Taiping's power was also strengthened. However, Princess Taiping was later dissatisfied with Li Longji's power and planned to seize the throne, but was eventually eliminated by Li Longji. After Li Longji became the emperor of the Tang Dynasty, he ordered Princess Taiping to die. As for why Li Longji wanted to kill Princess Taiping and all her sons, the literature did not provide a clear answer.
