@beijingchina_066: The hole in this building is there for a reason 🕳️ Shanghai World Financial Center — 492m, and that opening at the top isn't decoration. It's a wind aperture that lets air pass through instead of pushing against the tower 💨 The original design was a circle. It was changed to a trapezoid after public objections 😳 Locals call it the bottle opener 🍾 Glass-floor observation bridge at 474m 👀 #shanghai #china #chinatravel #architecture #swfc #lujiazui #pudong
