"The Signal of the Stomach, the Direction of Home" focuses on the family of Chen Meihua, a laid-off female worker in Jiangcheng in 2025: the breakfast stall faces environmental rectification, the couple tries live broadcasting for a living and responds to the factory's AI changes; the children are caught in educational involution and cyber violence, and the elderly face demolition and Alzheimer's disease. In the face of policy fluctuations and the impact of science and technology, the family resolves conflicts with fireworks and fights the pain of the times with family affection, reflecting the survival wisdom and social changes of ordinary families.
