Jiang Li, a woman whose name sounds gentle and picturesque, but whose actions are as decisive as a knife. She is not a time traveler, she does not have a system, and she does not have a golden finger to predict the future. All she has is a brain that spins faster than a CPU, and a pair of eyes that can turn boring data into real money. Two years after graduation, she was promoted from an ordinary coder to the backbone of the department, but she was suppressed under the ceiling because of her gender and seniority. Until that day, the core algorithm she developed herself was stolen by her boss, who in turn mocked her that "women should just keep to themselves." Jiang Li smiled, cold and dangerous. Keep to yourself? These four words were never in her dictionary. In a rage, she resigned, and despite everyone's doubts, she took her only savings and plunged into the "sunset industry" that was denounced by countless people - smart home. Everyone thinks she is crazy. A coder wants to work on hardware? Isn't this courting death? Her former colleagues whispered in the tea room: "Look, women are impulsive and will come back sooner or later to beg us." However, they were wrong. Jiangli's "sunset industry" is no ordinary sunset. What she likes is traditional home furnishing companies' rejection of AI and their indifference to user experience. She pulled up a grassroots team composed of a few technical geeks and a group of "old fritters" who had been eliminated by large companies. No VC backing? It doesn't matter, she writes the code by herself, goes to the market by herself, and even goes to discuss molds with the factory masters in person. Others raised tens of millions of dollars, but she relied on one exquisite business model after another to spend every penny wisely.
