I don't recall seeing such contrails during landing/takeoff of the 2001/2002 prototype.

This occurs when the relative humidity of the air is very high. The pressure in the wing tip vortices is low and so the temperature is low too and this causes condensation.
Oh ... And me again
Very nice Deino, I need to go to the book store in Springfield to pick up the article, I'm always glad to read your take and look at the very pretty aircraft pictures, maybe Chengdu/PLAAF will pick up on the Brat's suggestion that you be invited for an official introduction/factory tour, so that you might "formally" introduce this aircraft to the aviation world at large. This would be a brilliant move on their part, and a "blast" for you, you work so hard to write a fair and honest assessment of all the changes, and I do enjoy reading your articles as I feel that "you're one of ours", and it makes me very proud that we get to "share" this with you. Keep up the good work Deino, and congratulations again.
He's right of course Quickie, and those vortices are lift, he is likely "pulling a little g" as he accelerates off the deck you will notice the gear is "in transit" the burners are still likely in full, and he is pulling the nose to the vertical to keep the aircraft pitch angle steep, in order to keep the speed down. Once he has a little altitude, he will pull the thrust levers out of "burner", (as any engine issue is "more likely" at that first power reduction), and reduce the throttle to a high dry thrust, in order to keep from having to pitch the aircraft to a very high pitch angle to keep the speed down. You may recall that I have stated that I can "see lift", in this picture it is on full display for all to see, if you watch a few videos of the Eurofighter, Rafael, F-15s, J-11s, J-10s, you will note these vapor clouds rolling off the wings. I will never forget the first time I saw a C-130 pulling some g and these same contrails rolling off the wing tips as he was in a 30+ bank over our house in Tennessee. I was about 10 at the time, and deeply in love with airplanes and flying..... +++++..... , good memories, and the J-20 is making memories for us today...enjoy!
The fit and finish are stunning.
Also seems the engine has an adapter structure that different types of engines can simply "plug and play"

Fit and finish are critical. These later units are definitely pushing cross section reduction where the earlier units were in retrospect meant more as proof of flight systems and configuration.
Where do you see plug and play.
