The 2016 World AIDS Day on Thursday will be a bit different for Liu Shi, a 24-year-old gay man, who is HIV-positive.

He will host a talk show about his own experience and HIV/AIDS prevention in a temporary glass room set up in a plaza in Sanlitun, a bustling commercial district in Beijing. The show will also be available live-streaming online.

"I feel a bit upset now, since there are usually lots of people in that area and they can see me through the glass," said Liu Shi, who works full time at a private nonprofit organization that provides support for AIDS patients in the capital.
