As you walk down the candle-lit, tunnel-like path to Chuan Spa at The Langham, Xintiandi, Shanghai, you’ll feel like you’re in a wintry forest. Trees with bare branches sprout up from piles of white rocks, and everything is covered in white. The snow-colored treatment rooms have the same calming look. Warm up with indulgent treatments like Chuan Tao of Deto, which includes a body exfoliation, a warm algae wrap, an acupressure massage and an oxygenating facial.
