In the vast universe, the birth and death of a galaxy are just a moment of mottled light.Looking up at the stars, there is always a kind of sadness that is destined to be the ending. Where are you and I in thousands of years?The country, the flames of civilization, and the earth are just a speck of dust in the deep space.A moment of the starry sky, a thousand years on earth.The insects chirping forever will never fall, and you and I are fighting for the passing of each other.What exactly is at the end of the deep sky?
