Gradually, the sun sank into the western mountains, but it still left a translucent red light band around it, illuminating half of the sky. You can imagine the unique style of the sun behind the mountains. The sky is much more beautiful and lovely at this time. The dark gray sky is edged with that red strip of light, which is a gift from the sun to the earth. Above the light strip is the sky whitened by the sun, and above that is the dark blue night. There are still faint wisps of purple light at the intersection of gray and red. This is a colorful world, more magnificent than the scene just now. This light adds a lot of color to the dark gray sky, leaves brilliance on the earth, and leaves people with nostalgia for the sun and expectations for tomorrow.
