From March to April every year, Juyongguan, which is known as the "first pass in the world," is surrounded by a huge sea of shallow pink and snow-white mountain apricot blossoms. Flowers all over the mountains contrast with the vicissitudes of the ancient Great Wall, creating a stunning view. In addition, there is a train called "Train for Spring" passing through this place. The train makes its way slowly through the sea of flowers, looking like a walking loong from a distance. Take the train to cross the sea of flowers and experience the gorgeous scenery!
