As I said before, there's a full scale training of loading the space station core module onto the CZ-5. It seem to have completed. The words on CZ-5 says China Manned Space Flight with the CSS logo.

A few words on the CZ-7A launch failure. No official words yet, but from what is known the failure is in the separation of the first and second stage causing the second stage to lose control and exploded. Words are the problem lies with the new separation mechanism, the first stage, which is the CZ-5 boosters, completed its burning successfully, so it's unlikely to impact CZ-5. If the problem lies in the separation mechanism, not the second stage, it won't affect CZ-7 either.

However the payload is a very high value satellite, so it's still a very huge loss.
