In an ordinary city, 32-year-old courier Zhou Yuan spends his days rushing around delivering packages and his evenings sitting in the front row of an adult night school, studying logistics management and practical writing. He struggles to balance the demands of an exhausting job, his educational shortcomings, misunderstandings with colleagues, and family pressures. His journey begins when he enrolls in night school. By applying his newfound knowledge to solve problems at his delivery station, clear up misunderstandings, and inspire his colleagues to grow together, he eventually passes his graduation assessment, earns an opportunity for promotion, and becomes a symbol of an ordinary city worker striving to build a better future through hard work.
