Tang Minghuang(唐明皇):
In Chinese, it is pronounced as: táng míng huáng，Written as:

Tang Minghuang, also known as Emperor Xuanzong Li Longji, was a renowned emperor of the Tang Dynasty, ruling from 712 to 756 AD. During his reign, the Tang Dynasty reached its zenith, but it also began to decline following the Anshi Rebellion.
Li Longji was the third son of Emperor Ruizong Li Dan and demonstrated exceptional talent and political acumen from a young age. During the reign of Emperor Zhongzong of Tang, he played a significant role in quelling the coup led by Empress Wei, helping his father, Li Dan, to regain the throne and earning the title Prince of Linzi.
In 712 AD, Li Longji ascended to the throne, adopting the era name “Kaiyuan,” and he is historically known as Emperor Xuanzong. In the early part of his reign, he vigorously implemented reforms, appointed capable officials, curbed the power of eunuchs, reorganized bureaucratic institutions, developed the economy, and promoted cultural prosperity, a period known as the “Kaiyuan Prosperity.” During this time, the Tang Dynasty achieved remarkable accomplishments in politics, economics, culture, and other fields.
Emperor Xuanzong placed great trust in capable ministers like Yao Chong, Song Jing, and Zhang Jiuling, initiating a series of reform measures that streamlined institutions and improved administrative efficiency. The Kaiyuan era saw significant development in agriculture, handicrafts, and commerce, leading to social wealth, population growth, and a well-stocked national treasury. Emperor Xuanzong himself was a patron of the arts, supporting and promoting the flourishing of poetry, music, dance, and painting during his time, particularly poetry. He had close interactions with great poets like Li Bai and Du Fu. However, in the later years of his reign, Emperor Xuanzong gradually neglected state affairs, favoring Yang Guifei and her family, and appointing unworthy officials like Li Linfu and Yang Guozhong, which led to corruption in the court.
In 755 AD, the rebellion led by An Lushan and Shi Siming, known as the “Anshi Rebellion,” erupted. Emperor Xuanzong was forced to flee to Sichuan and eventually abdicated in favor of his son Li Heng (Emperor Suzong).
Emperor Xuanzong spent his remaining years in Sichuan and died in 762 AD at the age of 78. Despite the mistakes in the later part of his reign that led to the decline of the Tang Dynasty from its peak, his earlier achievements still make him one of the most famous emperors in Chinese history.
The reign of Emperor Xuanzong represents an important period in Chinese history, marked by both the glorious “Kaiyuan Prosperity” and the tragic “Anshi Rebellion.” His story reflects the rise and challenges of a dynasty and is a crucial figure in the study of Tang Dynasty history.
