What was the transformation of Yuanmingyuan during the Qianlong period?

After Emperor Qianlong ascended the throne, he spent several years building Yuanmingyuan, repairing porcelain every day, digging water and moving stones, costing millions.

Not only the garden landscape in Yuanmingyuan was adjusted, but also the architectural groups were increased. Changchun Garden and Qichun Garden were built in the east and southeast of Yuanmingyuan. These three gardens, all under the management of the management minister of Yuanmingyuan, are called Yuanming Three Gardens.

Changchun Garden, formerly known as Dongyuan, is about 220 meters long from north to south and 95 meters wide from east to west. The original building area is 2750 square meters, covering an area of about 2 1 000 square meters, which is equivalent to 1/5 of the total area of Yuanmingyuan.
