At twenty-two, Shen Zhixing graduated straight into unemployment. He slung an old backpack over his shoulders and began with a night hike up Huangshan. Over the next three and a half years, he traveled across China and around the world. From being ignored by everyone to gaining a hundred million followers, he was no idol, just a man who kept walking. And by walking, he broke free of his cage, returned to nature, and became a guiding light in the hearts of countless young people.
