Dressed in a dark blue waterproof jacket，outdoor shoes and a small backpack，25-year-old Ye Tian tries to get in an abandoned coking plant （焦化廠(chǎng)） in Beijing.
   An intern （實(shí)習(xí)生） for a German company in Beijing，Ye is among thousands of youth interested in city adventures，what they call "urban exploration"- "urbex" for short.
   The aim of this trending hobby is to explore structures- usually abandoned ruins or hidden areas of the manmade environment.
   Urban explorers are interested in these sites because they can understand cities from a different angle.Ye，for example，said he enjoyed the contrast between Beijing's two sides.
   "Widely known scenic spots and historical sites can only reflect the bright side of the city，or what the city wants you to see，" Ye said. "But abandoned places show you the past that is hidden deep in people's memories."
   In the eyes of Pan Ran，who is in her early 30s and works in Canada，an abandoned building can also evoke the spirits of those who lived and worked there.
   "There are diaries and letters recording the owners' lives，" she said. "And one time，I found a whole box of 8-millimeter videotapes of a family."
   Pan couldn't watch the tapes at the site，as the power supply had been cut.She didn't take them away with her either，as there is "a very important rule of urbex that you can't remove any souvenirs' from a site"，Pan said.
   While urban exploration can get people to extraordinary places that few have visited，it's sometimes dangerous.Climbing up tall buildings and tip-toeing through abandoned structures can sometimes be a life-threatening affair.
   Injuries and even death are not unheard of within the urbex community.
"In the beginning，I was pretty audacious and believed the riskier the places you go，the better photos you get，" said Du Tianyu，22. "But that is not necessarily the case.After doing my calculations，I learned to stop when I reach the limit."
