Chen Xiao, a former product manager who became a food delivery rider after being laid off, used algorithms to optimize delivery routes and accidentally exposed the company's squeeze mechanism. He was dubbed the "rider's magic calculator" by the entire Internet. When platform director Lin Zhao knelt down and begged him to be reinstated, he chose to disclose all the data on a rainy night. What really tore the company apart was the recording of the single mother rider A Yao hidden in her work badge and the fallen figure of Lao Dao, a ten-year-old rider. This is not a story of reinstatement, but a war in which the bottom rewrites the rules with flesh and blood.
