Emperor Qianlong lived from 1711 to 1799, and the Jiachen year was 1724 and 1784 respectively. According to Qianlong's accession age of 25 years, the Jiachen year of Qianlong should be 1784.

Aixinjueluo Hongli (Qing Emperor Gaozong, September 25, 1711 - February 7, 1799), was born in Prince Yong's Mansion (today's Lama Temple) in Beijing. He was the fourth son of Emperor Yongzheng and the sixth emperor of the Qing Dynasty.

The reign name "Qianlong" was the emperor who actually held the highest power of the country for the longest time and the longest life in Chinese history.

During the reign of Hongli, martial arts flourished and established the territory of modern China. With emphasis on social and economic development, the Qing Dynasty reached the highest peak of the Kangxi and Qianlong periods.

But in his later period, he was extravagant, his administration was corrupted, and uprisings broke out in many places.

Seclusion has widened the gap with the West.

When Hongli died in 1799, he was named Gaozong (posthumously named Fa Tian Long Yun Zhi Cheng Xian Jue Ti Yuan Li Ji Fu Wen Fen Wu Qin Ming Xiao Compassion Sheng Sheng Chun Emperor) and was buried in Yuling in the Eastern Tomb of the Qing Dynasty.
