There is actually a pretty good comment about how to get to the moon without building a (4,000 ton class) moon-rocket:Lol, so many sour grapes in the comment section.
We already know the Chinese plan on EOR assembly of larger spacecraft such as a space station, via modules launched by CZ-5.
With that in mind, it's interesting to speculate what else the Chinese might try in the future using the CZ-5 and EOR assembly. (I for one, don't expect the Long March 9 to ever be a factor)
I couldn't help but notice the CZ-5 second stage is slightly lighter than the LEO payload capacity of the CZ-5. So in theory, a CZ-5 could loft a fully fueled EDS stage into a parking orbit which is based on the CZ-5 second stage (with docking hardware and perhaps solar power).
Such a Chinese Earth Departure Stage would be adequate for all sorts of interesting cislunar manned missions.
