Having dropped out of school at a young age, protagonist Li Xuan heads to Shenzhen, Guangdong, to work in a factory. He goes through one experience after another: first, his first love, Lin Luodan, betrays him; then he meets Lin Yan'er, the factory beauty with multiple personalities; and finally, he meets Xia Yuanxi, the white-collar worker he will love for the rest of his life. He also meets the first mentor of his life, Song Yunfu, as well as his always-befuddled but sweet and innocent little cousin, Luo Yufei, and his stern second sister, who has taken over their mother's role and keeps a close eye on him. See how he transforms in the big city!
