@beijingchina_066: The youngest big city in the world 👶 Shenzhen — average age is around 32. Most cities this size are full of families who've been there for generations. Shenzhen has almost none 😳 Why? Everyone here moved from somewhere else. The city didn't exist 45 years ago. Locals joke that if you're 40, you're the old guard 😂 A city with no history, building one right now 📍 #shenzhen #china #chinatravel #architecture #citylife #nightview #skyline
