are they waiting to see how this one performs before starting construction on the next one? they should overlap the constructions otherwise it would take too long to form a fleet with 6+ carriers.
Given how China is still somewhat of a newbie when it comes to aircraft carrier and carrier-based aviation operations, coupled with the PLAN's typical cautious, 小步快跑's nature - I'd think that we should be thankful if we can see 5 carrier hulls in the water by 2035.
Unless, of course, if the PLAN is finally satisfied with the 004 (if the 4th CV is a half-sister to Fujian) or the 005 (with the 4th CV also being a one-off ship, whether nuclear-powered or conventionally-powered) such that subsequent CVs can be put into serial production, then we might be able to see more than 5 CVs existing in various states by 2035.
