We know even LESS about the Shenzhou, other than that it's based on Soyuz, with bigger (in comparison to Soyuz) Orbital module that carried its own Solar panels, controls, and thrusters and can fly on its own, and it allegedly "provide experimentation capability". The only thing confirmed is that one of the Orbital Module stayed up there by itself for few months for some experiment.
That being said, it's not a improbability, since Gemini MOL is a Spacelab in itself.
If we are tallkign about SpaceLab, it has at most an equivalent capability to Salyut.
If we are talking about ISS building (vs Mir, etc), it's the module itself, which I think is independent of Shuttle.
It's not just space program, In some place, you have politician confusing a bike and full-size pickup truck, and people keep voting them in three times. Oh, and some people believe that it's okay to cook with electricity only.
