Starting from different ramps, they pass by each other and eventually meet at the top of the tower

At one end of the corridor in the Sihang City of Shanghai's Qiantan, sits a giant red double helix tower named 'The Endless Spiral'💫 This public art installation, inspired by the infinity symbol '∞' of the Mobius strip, allows people to start from two different ramps of the double helix, passing by each other, and eventually meeting at the top of the tower💃
