Emperor Qianlong, Emperor Gaozong of the Qing Dynasty, was the founder of the territory of the Qing Dynasty. All the territory of China recognized by modern China people was laid in Qianlong. Aisingiorro Hongli was born in August of the fiftieth year of Kangxi (17 1 1) and died in the first month of Jiaqing (1799). He was the sixth emperor of the Qing Dynasty and the fourth emperor after entering the customs. He is the fourth son of Yong Zhengdi Rabbit. He was born in Qin Yong Palace in the 50th year of Kangxi (17 1 1). In the first year of Yongzheng (1723), Li Hong was made a prince, and in the eleventh year, he was made a prince and a master, and began to participate in military affairs. In the 13th year of Yongzheng (1735), Yongzheng died, Li Hong ascended the throne, and changed his title to Qianlong. So, he stood at the highest point of China society at that time, and began to exert his "Wen Zhi Kung Fu". Qianlong reigned for 60 years, and after abdicating, he became the emperor's father for three years. He died of illness at the age of 89. Buried in Yuling (now Changrui Mountain, 70 miles northwest of Zunhua, Hebei). Posthumous title Fa Tianlong was transported to Zhicheng Wushen, Fenzhou, Wu, filial piety and fine emperor, temple name, and was called Emperor Qianlong in history. At the same time, he is also the longest-lived emperor in the history of China. His 60-year-long stable rule was an era of long-term precipitation of China's feudal politics, economy and culture. The last years of Qianlong were also a transitional period from prosperity to decline in Qing Dynasty. After 60 years in power, Emperor Qianlong ruled for three years (that is, the actual rule of Emperor Qianlong lasted until his death), although Zen was with his son Jiaqing. Therefore, Li Hong was the longest reigning emperor in the history of China. Actually in power for 63 years. Emperor Qianlong was charming and good at riding and shooting. He wrote poetry all his life, and his pen and ink stayed in the north and south of the river. His poems have reached more than 42 thousand, which is very different from the whole Tang poetry. Emperor Qianlong attached great importance to the collection of cultural relics and ancient books, and most of the paintings and calligraphy in the Qing Dynasty were collected by him, so he ordered the collection of the inner government to be compiled into "Shiqu Baodi" and "Xiqing Ancient Mirror". Gan Long himself is a lover of ceramic art. During his administration, China's ceramic industry has made great progress. Today, some collections of the Qianlong Dynasty and ceramic palace utensils are still collected by the Palace Museum and the David Foundation in London. In the late Qianlong period, due to the increasingly acute social class contradictions, Emperor Qianlong gradually changed the previous practice of suppressing the lower intellectuals and turned to wooing the lower intellectuals. He gathered a large number of intellectuals together to compile large-scale classic books, such as Xu Diantong, Xu Zhitong and Xu Wentong. The most outstanding cultural achievements are: collecting books all over the country, organizing more than 360 people, including Dai Zhen, Yao Nai and Wang Sunnian, and taking the famous scholar Ji Yun as the president, which lasted 15 years and compiled the largest series Si Ku Quan Shu in the history of China. Sikuquanshu has 36,000 volumes, including 3,450 complete works, which is three times as long as Yongle Dadian, and its length is the longest in China. This book comprehensively summarizes the previous studies, retains a large number of valuable ancient books, makes important contributions to the collation and summary of ancient books and cultural heritage, and becomes a master of China's ancient ideological and cultural heritage.

The forest palace in the east, the restoration hall in the west, the worship platform in the south and the Jiege in the north are endless and magnificent. After a bachelor of arts and a skilled craftsman, I spent countless efforts. Digging a pool here, piling stones there, planting forests here and planting flowers there are full of beauty and embellishment, regardless of spring, summer, autumn and winter. And instructed local officials in all provinces to collect rare birds, exotic flowers and ancient ding, and to display the treasures of nine Wan Li at home and abroad and the treasures of five thousand years in the garden. Therefore, Yuanmingyuan is also known as the Oriental Art Museum all over the world. 1750, Qianlong entrusted Italian Catholic priest Lang Shining to design a timed water clock and fountain device for royal entertainment. At the same time, Qianlong's perspective was limited to China, and he didn't know enough about the science and culture of European countries which were booming in the same period.
