Gong Yifei swapped life as an armed police officer for a precarious career as a pole-dancing trainer - and he wants pole-dancing to be respected as an art.
If you take pole-dancing seriously, two little rooms tucked away on the top floor of a shopping mall in Beijing are where you train.
Apart from a few scantily-clad women, there is little to suggest this is the headquarters of China's first and biggest chain of pole-dancing training centres, the Luolan Pole Dancing Club.
Step inside and you see a forest of steel poles. A few women are warming up. One person stands out. He is the only man in sight and his name is Gong Yifei.
