Helian came to the small town of Duolong with his father's transfer. The town still retains many old customs and buildings. There is a Chang'an Street in the town, where people live forever. Their stories slowly unfold in front of Helian like a scroll of calligraphy and painting... With his father being transferred again, Helian left the town, and the ship sailed towards the sky. Behind Helian was the ancient Jiangnan town, the sleeves of elegant young men rolling in the wind, and the lonely back of a woman in red.
