Guangdong TV presenter Ou Zhihang is a man on a mission, highlighting issues in Hong Kong and the mainland one naked press-up at a time. Hannah Xu reports

Hong Kong's streets are littered with debris; plastic bags, newspapers and tree branches are being flung through the air as Typhoon Vicente batters the city.
Outside Kowloon Tong's Baptist University, Ou Zhihang is on a mission. He finds what he's looking for on Junction Road, picking a spot near a big fallen tree, facing Shaw Tower, the university's administration building.
He erects a tripod nearby and has trouble setting his camera as the light comes and goes with the downpours. Holding an umbrella, he stands behind the camera, waiting for the rain to become lighter. Waiting has never been a big deal for Ou.
Forty minutes pass.
Finally, the moment he has been waiting for arrives. He presses down the camera's shutter button, takes off all of his clothes, runs in a crouch to his chosen spot and does a single press-up.

had been planning to visit Hong Kong since late last year, when debate over the city's adoption of a national education curriculum began in earnest. In April, when the arguments began to get heated (on May 7, even the People's Daily in Beijing ran an article that used the word "brainwashing" in connection with the curriculum), Ou was certain the trip would be made soon.
