Roof-topping enthusiast Daniel Lau takes a selfie with high-rise buildings down below as he stands on the top of a skyscraper in Hong Kong, China on August 15, 2017. Welcome to “roof-topping”, where daredevils take pictures of themselves standing on the tops of tall buildings, or in some cases even dangling from them, without any safety equipment. A craze that began in Russia has now taken hold in Hong Kong, one of the world's most vertical cities, with dramatic results. “I'm an explorer”, said Daniel Lau, one of the three who climbed to the top of The Center. A student, he said roof-topping was “a getaway from my structured life”. “Before doing this, I lived like an ordinary person, having a boring life”, he said. “I wanted to do something special, something memorable. I want to let people see Hong Kong, the place they are living, from a new perspective”. Mr Lau said he had been inspired by Russian climbers and that he was unafraid of the vertiginous heights he scales. (Photo by ImagineChina/Rex Features/Shutterstock)
