Against the backdrop of modern rural agricultural industrialization, Gao Chengyu, a young man who returned to his hometown, mortgaged his property and invested 950,000 yuan to build a temperature-controlled storage facility, a grading line, and a processing workshop in Heitugou. He personally sought out distribution channels, conducted inspections, and negotiated orders, raising the village's potato purchase price from just over 0.4 yuan per jin in previous years to 0.85 yuan. Hoping to help his fellow villagers escape the middlemen's price suppression, he instead faced a backlash at the critical time for potato sales. Villagers such as Zhao Fugui, incited by the claims of Qian Laosan, an out-of-town trader, that potatoes were being sold at high prices in the city, blocked the storage facility's entrance and demanded that Gao Chengyu pay them the price difference.
