Maybe it is all photo shopped, maybe not. The consensus of the various authors is that it is not.

James Fallows wrote that the Chinese can get things into production and onto the streets very fast, faster than us. He gave an example of their having a knockoff of a new American electronic product on the street a day or two after the product launch of the American model. And the Chinese knockoff had more features. That may have some bearing on how fast they can get a new fighter into operation.
