If I'm not mistaken, then this is the first image not only clearly showing Z-8 (Z-8CJ ?) but even more that many - I see eight - ship-borne transport helicopters on deck of the first Type 075 LHD at Hainan.
Even if its serial number is once again psed, this is the first clear image on an operational PLA Army Aviation Z-8L - the wide-bode variant - with the typical LHXXXXX number visible.
Based on other reports this is something within the LH953txx range and as such assigned to the 161st Air Assault Brigade (83rd GA) at Xinxiang within the Central Theater Command.
