@beijingchina_066: Shenzhen built a whole metro system from scratch 🚇 First line opened in 2004. Today it's one of the largest networks in the world 😳 Because it's new, everything works: platform screen doors on every station, phone signal in the tunnels, air conditioning. Some lines run driverless 🤖 Cheaper than a coffee to cross the city 📍 #shenzhen #china #chinatravel #metro #transport #citylife #architecture
