Feng Lun, a seasoned Chinese entrepreneur and storyteller, lays bare the unspoken rules and hidden logic that shape everyday life in *The Logic of Life*. Drawing from decades of raw, personal experiences—from growing up with his mentally ill grandmother who clung to her pre-1950s memories, to navigating family conflicts, business scams, and high-stakes career twists—he unpacks the core logic behind everything from filial piety and healthy living to education, friendship, and the messy realities of capitalism. He doesn’t rely on dry theories; instead, he shares relatable, gritty stories: the medical scare that taught him to prioritize regular health check-ins, the hard lesson of falling for a fake AI startup, and how balancing proximity and space transformed his relationship with his parents. Covering everything from drinking etiquette and gift-giving dynamics to the nature of love, power, and modern philanthropy, Feng offers no-nonsense, practical insights that resonate across cultures. Whether you’re navigating family tensions, building a career, or just trying to make sense of life’s chaotic moments, this book is a down-to-earth guide to understanding the unwritten rules driving human behavior and decision-making.
