Screenwriter Liu Xiangshang has a relatively free schedule in his daily schedule. He is responsible for the education and care of his son Guo Ning and daughter Guo Bao at home. His wife Dai Jing chooses to work in a foreign company with higher salary. With the implementation of the double reduction policy, the original plans and arrangements are bound to be adjusted, and the couple have differences in their cognition and understanding of the policy. In the parent group, Liu Xueguan, an old father who came to help, said that the amount of homework should not be reduced, and some parents questioned the academic performance and test results. Influenced by these, Dai Jing gave up a high-paying job in another place and returned to her family to accompany her children to grow up. After a series of events, they realized that education requires the comprehensive development of morality, intelligence, physical fitness, aesthetics and labor. The family of four is enjoying the happy "double reduction" in learning and growing together.
