Sandy Lam, 68, hangs a towel to dry in the mens changing room at the Sai Wan Swimming Shed in Hong Kong, China, October 4, 2018. Lam said he has been coming to the swimming shed for 28 years. "We're all friends and we've known each other for a long time," he said. "We pay HK$150 ($19) per month which pays for the water and light in the shed, and for the changing rooms to be kept well."
