In 1998, Lin Chen, who had just lost his iron job, was cornered by debt collectors on a rainy night, but unexpectedly found an old deed that hid the property rights of an abandoned cannery. With the business memory of 2024, he used his only 300 yuan of living expenses to repair equipment, improve the formula, and pry open the market gap with a "nostalgic hawthorn can". Faced with the doubts of neighbors, the suppression of established manufacturers, and the hunting of capital giants, he seized the opportunity of the era of state-owned enterprise restructuring, the emergence of the Internet, and the rise of real estate. From small factories in county towns to chain brands, from physical industries to cross-border e-commerce, he ultimately created a global business empire spanning food, technology, and finance. The story contains the enthusiasm of grassroots counterattacks, the thrills of business war games, the struggle between individuals and fate in the tide of the times, and also contains the collective memory of opportunities, struggle and perseverance of a generation.
