In the early 1980s, the spring tide of reform surged. Xu Zhuohua, who returned from studying abroad, took the initiative to win orders for the factory and entered the technical team in order to track down the truth behind the disappearance of her father Xu Zhenguo, who served as the deputy director of the Swallow Dance Factory. Together with Lu Huaiyuan, the deputy director dedicated to reform—moving from mutual probing to mutual trust—they worked hand in hand to uncover the truth and promote product innovation. This not only brought her father safely back and rescued the factory from crisis, but their jointly developed "Swallow Dance" brand tape recorder swept across the country. The advertisement "Swallow Dance, Swallow Dance, a song comes with a flood of affection!" was broadcast on CCTV and sung throughout the north and south of China, propelling the Swallow Dance brand into glory. In the midst of their struggle, the two also grew into each other's lifelong partners.
