Amazing stuff! Basically, these ramps are made by a Chinese company called Soldierbar. I guess a lot of people think of China and instantly think of crappy mass produced products that aren't worth getting. But they go have a great scene too by the looks of things,with some interesting products, such as these awesome ramps! This park has stickers on it for something you can make out to say 'go finger skate day!' but I don't know when it is/was. Either way, its really interesting to see. Xi is Chinese, but used to live in England, and now he's back in China he's on a mission to connect the two scenes and hopefully get us both to recognise each other's riders and products. I think that'd be great! Here's (click me) a really interesting news video featuring some guys from this posted last month - he talks a lot of good stuff, from negative cheapy products, to making skateboarders in general not seen as a bad thing, to how he started fingerboarding and found videos of riders in our scenes to inspire him.
Good luck on your mission Xi! Go check more on this on FBHQ here :)
