The Flying Pigeon brand bicycle in Beijing could probably be found in one of those major bike shops like cycle world. I believe that's the name of the shop or it's close to it. I've seen a couple around and they have a large variety of bikes to choose from. If they don't have it I think you would be $h!T out of Luck!

Do you have a photo?  Why are you interested in this particular brand btw?

Not in Beijing, however in Hankou Wuhan, the nearest Flying Pigeon store on Zhongshan Rd, is only a 5 minute walk from me. I actually paid a visit to it on Monday last,
