Why did the emperors of the Qing Dynasty build royal gardens in Haidian area?

1. Practical reasons:

The wind in Beijing is mainly from the northwest, and the river flows from west to east.

Haidian is located on the upper side of Beijing, at Sheung Shui Kou.

The royal gardens are built in Haidian, so the quality of air and water can be more easily guaranteed.

2. Feng Shui factors

The northwest belongs to the Qian position, which belongs to the male position. The royal garden occupies the Qian position, which is conducive to strengthening the imperial power, which is the so-called ascendancy.
