Editor's Note: What does it really take to turn a grassroots sports boom into a sustainable service industry? And how can youth development help drive not just future champions, but also a thriving holiday economy? In this episode of The Hub, Wang Guan explores how sports — as a fast-evolving part of China's service sector — is creating new momentum, from ice sports gaining traction among families to AI-powered training tools reshaping grassroots access. Wang Guan is also joined by former international footballer and coach Sun Jihai for an in-depth conversation on the challenges and opportunities facing Chinese football today. Together, they show how getting youth development right isn't just about medals — it's about a more innovative, people-centered service economy in action.
