USSR and Russia followed US Navy carrier groups for 30+ years with fishing trawlers/AGI, trying to learn and figure out how US Navy conduct carrier operations(besides trying to know where carrier groups are at all time). So when Russia got its own full size carrier in early 1990s, Soviet Navy already got years of experiences by already operating 4 Kiev class VTOL carriers(1975 to 1995) and 2 Moskva class ASW helicopter carriers(1967 to late 1990s), but Russia still having problems operate a full size carrier and its air wing.
Put PLAN into the picture, god knows how long will it take for PLAN to learn the rope.....
