In a courtyard house in old Beijing, He Yuzhu, a skilled cook, lives alone. He is enthusiastic and righteous but is often plotted against by his neighbors. Trivial matters in various families in the hospital are constant, disputes between right and wrong are staged in turn, and the warmth and warmth of human relationships are displayed here one by one. He cared about Qin Huairu, who was struggling to survive with her children, and helped her all year round. The two relied on each other amidst rumors and the pressure of life. As time goes by, quarrels and tenderness are intertwined, and after countless storms, everyone experiences the various fireworks in a small courtyard, understands human nature among parents and friends, and waits for the long-lasting warmth.
