The most beautiful moment in a city must be after sunset, when the lantern is first. Every street in the city is embellished with beige lights. Night scenes, like the elves in the dark, each city has a unique night scene. In the night, the ancient city wall is being rebuilt, which is also the most complete and spectacular wall in the country. As the northern part of the town, the city of Datong is arrogant, heavy and majestic. Looking out from the wall, you can see the street extending far away. Compared to the hustle and bustle of the day, there is more silence at this time.
