@beijingchina_066: Beijing is the only city to host both Olympics 🥇 Summer 2008 and Winter 2022 — nowhere else has done both 😳 The Bird's Nest stadium: 42,000 tonnes of steel woven into a lattice with no internal columns 🪺 The Water Cube next door is wrapped in bubbles — a pattern based on how soap foam actually packs together 🫧 Both still standing in Chaoyang 📍 #beijing #chaoyang #birdsnest #olympics #china #chinatravel #architecture
