Young craftsman Wang Zaihang leads a small team facing a month-long predicament of having no stable orders. Starting with leftover waste materials such as wood scraps, bamboo pieces, and fabric remnants, the group reforms and polishes issues like packaging loss, and develops three small items—coasters, hanging clips, and storage trays—based on the dimensions of the surplus materials. After enduring multiple prototyping failures and craft improvements, they visit stores, markets, and community experience centers. Relying on small, steady supplies and attentive maintenance of regular customers, they walk out of the business trough. In the process of cost-cutting and deeply cultivating the market, they learn to balance craftsmanship, cost, and long-term development, completing a down-to-earth growth transformation.
