In 1976, a 7.8-magnitude earthquake buried Wang Daming and Lin Zhiyan in the mine hospital. Six days and seven nights later, Wang Daming was rescued and woke up to learn that his pregnant wife and father were gone. Neighbors were in mourning. During the days of selfless work after the earthquake, Yang Ai, a female worker at a ceramic factory, broke into Wang Daming's life. Yang Ai's parents died, and her eldest sister's family died in the earthquake, leaving behind only a young son who became mute due to the earthquake. Wang Daming and Yang Ai became a half-way couple. The Wang family and the Lin family have become a family together. In addition to mother Feng Lanzhi, father-in-law Lin Zhaorui, brother-in-law Lin Zhicheng, younger sister Wang Weidong, and the two half-grown boys from the neighboring Liu family who were just adopted, there are now three new members - Yang Ai's two sisters and the little mute Sun Lei. A family of nine with six surnames, a non-blood-related family, went through earthquakes, SARS, emotional entanglements and cancer torture. In the era of reform and opening up, they broke free from the post-earthquake difficulties and finally rebuilt a happy home.
