The volunteers I trained for the Shanghai World Expo have returned to Hong Kong with clear growth in professional competence, international exposure, and public‑service understanding. They shared valuable insights on the volunteer systems of Shanghai and Hong Kong, exhibition‑driven economies, and the role of commercial diplomacy. It was also inspiring to see CUHK students contributing with strong professionalism, and I look forward to more young people engaging in global platforms and bringing their learnings back to Hong Kong.
