One of my most visited places for finding eternal peace is the Yanqi Lake Scenic Area, as it is within my cycling range and is very soothing. When I sit on the very wide wall of the dam of the lake, I can inhale the purest air, drawn from the mountain ranges in front of me; I feel I am in heaven. The stress from the whole week is gone instantly. Also, I enjoy the scenic view of the surrounding area when I visit Yanqi Lake, especially in the afternoon till evening, and I come back to my dormitory before it gets dark.
The night views are not as natural, since the lake completely darkens at night, but I have found that the lakeside resorts and hotels, along with the smaller island inside the lake, create an artistic view that is stunning. For the first time, it was unbelievable for me, and it was hard to believe my eyes with the amazing beauty of the night. The colourful lighting on the mountains and their reflection in the lake water seem to be among the best views you can enjoy here.

Dear @tanzil2024 !
Hassan!
Why is Yanqi Lake lit up with electricity at night?
Since Yanqi Lake is a tourist attraction, do they have electric lights on?
