Lin Chuan faced setbacks at work and returned to Qingling Village, just as his father's mountain grapes were facing continuous rain, fruit splitting, and falling price problems. He teamed up with Zhou Ning, wanting to use packaging experience to open up sales channels, but encountered transportation loss issues. After trial sales, he took the initiative to refund, creating a conflict with his father. Lin Chuan realized he needed to optimize the entire process from picking to selling, implementing fruit grading and limited sales. Heavy rain led to a reduction in first-grade fruit production, but he adhered to quality, adjusted channels, and maintained customer trust. After a season of trial and error, everyone recognized the grading standards. The next year, Lin Chuan stayed in the village and no longer regarded returning home as a fallback. Father and son worked together with one heart to control quality, and he understood that returning home to start a business has no shortcuts, only down-to-earth and deep cultivation.
