Its called Schichang (AH 82)Type 0891A (NATO call it Dashi).I recognise that ship on the left
its like the UK Bay Class ship with that terrible mid island structure
some sort of LPD hybrid
It was China's first aviation training ship, which may also be used to carry a containerised hospital.
In this respect it is like the Royal Fleet Auxiliary ship Argus. Neither ship have a dock.
