Actually vesicles was saying that the photo probably showed a museum (aka not an actual workshop or lab as part of SAC). I think that's a reasonable argument, but IMO everything in the photo could also be an actual lab or workshop as well.
The issue is what the visit was actually about -- I agree that civilians would not be let near any sensitive information, but at the same time there's nothing in the picture to suggest there is anything "sensitive".
The cockpit flight simulators are probably not particularly sensitive. The mock up of the potential JH-XX nose in the background is arguably the most "sensitive" -- but not necessarily because of what may be inside, but probably because of the fact that it exists in the first place, because if this photo was actually taken at SAC then the presence of that mock up means that they've likely done some research work into the aircraft in the past. Whether it means the project had since been cancelled with no active work on it at present, is another matter.
edit: also, what weapons bay photo are you talking about before?
Even if it's just a part of the JH-XX's nose, it is tacit acknowledgement that the project exists, which would be a fairly major reveal and unlike the historical practices of SAC (or any other Chinese aviation institution). Hence, I now think that the model represents either a generic nondescript plane or perhaps a cancelled proposal for the JH-XX.
