Under the old locust trees in the old city, the youth of three teenagers is hidden. Su Xiaowen, a scholar from a poor family, gnawed on a piece of bread and copied a book, with the suffering of the people and his dream of taking the imperial examination in his heart; Lin Laosan, the carpenter, wielded an axe, chiseling wood, carrying brotherly loyalty and a promise of a large sum of money on his shoulders; Shen Fugui, a son from a rich family, climbed over the wall with snacks in his pocket, his eyes filled with sincerity, innocence and perseverance. An autumn list represents the bitterness of more than ten years of cold weather, the warmth of three people walking together, and the starting point for young people to move from the old city to the distance. The joys and sorrows under the red wall have come to an end, but their story has just begun - on the road to fame and fame, the friendship remains; in the fireworks of the world, the young man sings.
