The following are classic and beautiful sentences that can be used in urban novels: The world of mortals is beyond the horizon, the misty waves are boundless, and I stand alone in the sky, free and easy. When the lights are waning, I suddenly look back, but that person is there. Where can I find my true self in the golden age of vanity? Behind the pomp and glory, only loneliness can be seen. The night is long and lonely, I sit alone in front of the window, thinking of thousands of things. Time is like a song, life is like a dream, looking back on the past, I feel very emotional. The world of mortals is fortunate enough to know the white-haired, don't separate from each other, longing for a long time to accompany each other all the way. The mask behind the vanity has been worn for too long, but it is difficult to take it off. The ups and downs of the mortal world, through the wind and rain, still have warmth in my heart, moving forward. The petals of fallen flowers fall in profusion, how many sorrows of parting turn into butterflies fluttering. There will be a time when the wind blows and the waves break. The clouds sail straight across the sea. If there is a will, it will be done.
