Jiang Yan's window glass was double-glazed.
It was heat-insulating, cold-insulating, and bulletproof.
Besides, she had the decoration company apply a layer of the latest foreign-developed single-directional composite glass film, originally used on high-end cars, on the outside.
This film not only had excellent heat and cold insulation effects but also had a special feature, allowing her to see outside clearly.
However, for those outside, even if she didn't draw the curtains, her room appeared entirely dark.
The privacy was exceptional.
This effectively prevented any nosy individuals from using telescopes or flying drones to "spy."
After adjusting the telescope's pupil distance and various parameters, Jiang Yan looked towards the group of people in the garden.
There seemed to be several officials in white shirts and black trousers talking to the property management staff.
The property manager and several supervisors were also present.
