In the early 1980s, in the courtyard of Hongguang Machinery Factory, three families, Liu Shuxia, Wang Xianping, Dongfang Yushu, and Yang Dashan, welcomed their children on the same day. Spanning the 1980s and 1990s to the new century, the two generations have gone through neighborhood fireworks, conflicts between husband and wife, children's growth, youthful regrets, and the pain of birth and death. Parents have to face conflicts in work, livelihood, and marriage; children like Wang Xuehua, Dongfang Hong, Yan Bing, and Yang Siyu have experienced childhood sweethearts, misunderstandings, misses, and endured heavy trauma in their youth. There are gentle and heart-breaking joys and sorrows hidden in ordinary days.
