@beijingchina_066: You can walk around the OUTSIDE of this building 😳 Jin Mao Tower, Shanghai — there's a 1.2m-wide open-air walkway circling the 88th floor, 340m above the ground 🚶 No glass. Just a harness and the city below you. Inside, there's a hollow atrium dropping 33 floors straight down 👀 421m, built on the number eight 🔢 #shanghai #jinmaotower #china #chinatravel #architecture #skywalk #pudong
