Yuanmingyuan was mainly built in the last years of Kangxi and Yongzheng. In the forty-eighth year of Kangxi, Emperor Kangxi gave his fourth son Yong Zhengdi a garden in the north of Changchun Garden in the northwest suburb of Beijing, and personally named the garden "Yuanmingyuan". During the Yongzheng period, Yong Zhengdi ordered the expansion of Yuanmingyuan. The project consists of three parts: imitating the symmetrical shape of the central axis of the Forbidden City, extending the central axis to the south, building a palace area and opening a grand palace gate.

The second part, expanding to the east, west, north and south, building pavilions, pavilions, buildings and pavilions. The third part is to build Fuhai and its surrounding buildings. At this point, the expanded Yuanmingyuan covers an area of about 3,000 mu. At this point, the pattern of Yuanmingyuan has basically taken shape. After Emperor Qianlong succeeded to the throne, he adjusted the garden landscape in Yuanmingyuan, added new buildings, and built Changchun Garden and Qichun Garden in the east and southeast of Yuanmingyuan. This is what we know as Yuanming Three Gardens.
