Xu Guihe returns home to take over the old hawthorn workshop on the verge of stagnation, striving for a trial order opportunity of three hundred boxes from the supermarket. Rival Fang Jingshan creates difficulties everywhere, continuously manufacturing obstacles in raw materials, packaging, cost, and production links. The team breaks through the limitations of old craftsmanship relying on experience, establishes standardized production processes, improves raw material grading schemes, solves packaging and transportation hidden dangers, and faces all kinds of doubts head-on. After undergoing severe tests and completing the trial order delivery, they finally win a long-term supply contract from the supermarket, allowing the rural hawthorn industry to achieve an upgrade.
