Guancha team did their livestream last night mostly about Fujian, you can rewatch it here:
I like the part where they were shit talking Navy Lookout for his sour-ness.
There's also a exclusively on Fujian and PLAN carrier history on qingting, I'm still going through it at the moment. Yankee already revealed an interesting fact: the carrier version JL-10 isn't called JL-10J or JL-10H or anything like that, it actually has the rather weird name "教-15". The reason this thing hasn't shown up in Liaoning and Shandong is because their arresting wires are setup to handle J-15 exclusively and is too stiff for the smaller 教-15 (JL-15?). Fujian doesn't have this problem as its arresting wire resistance can be easily adjusted. There's no problem for 教-15 to take off from Liaoning and Shandong as it is.
I can only suspect that they are talking about some form of older arresting wires on CV-16/17 given we expect J-35/XY to be aboard them and obviously J-35/XY is not the same aircraft as J-15 meaning if CV-16/17's arresting wires are only capable of catching J-15 then they'd need to change them to one that's different.
