What do you mean with „another one“? Another new J-20 or a new unit? … any idea where this image was taken?

It looks to be the CAC facility and one of the nozzles is drooping, which is characteristic of TVC nozzle.

Another image,TVC nozzle looks different from the one on the J-10B(if this is a TVC nozzle),and the image I posted before could be years old(J-20 could have already tested that WS-10C+TVC nozzle combo before),I do think there’s a possibility that WS-15 has made its maiden flight on J-20 ,timeline just add up(3yrs from 2018),I’m sure more images with better quality will come out in a few days,cuz all the people who have seen them were very sure it was WS-15 instead of WS-10C
Thanks a lot and indeed, looks like a TVC-nozzle!
By the way, ... one of the clearest images of a WS-10C powered J-20A.
And as per image data by the photographer it was taken already on 7th July 2019.

Strongly suspect this nozzle is for the WS-19.
Nope,and it’s insane to assume that
How so?
That was a CGI of an engine whose dimensions and thrust rating that we do not know, and we certainly don't know it's identity.
It does obviously demonstrate TVC, which is something we expect on WS-15, but it's not yet known if we should expect TVC on WS-19 or not.
.... Personally I have no opinion on whether that CGI demonstrates WS-15, or WS-19, or whether it depicts anything at all. But I certainly don't think it's insane to believe that it could be any of those options.

I think @latenlazy was talking about @Xsizor 's CGI pic saying it is WS-19 but @Philister thought he was talking about Deino's most recent J-20 pic in yellow and said that it's insane to think that they had put WS-19 nozzles on the J-20. That's how I read it until I got things straight.
It’s a F414(EJ230 if being optimistic)class engine with a size of RD93,that’s for sure,it couldn’t possibly be fitted into a J-20 without major structural change.
WS-19 definitely comes with a TVC nozzle,they’ve shown it in CG at Zhuhai2018(if I remember correctly),yet that CG should be taken as an evidence that WS-19 will be equipped with a TVC nozzle but not too seriously,the nozzle could be different in reality(they do that A LOT,I’m sure you’ve seen the recent CZ-9 2021,yep,could happen but the chance is just not good)
And the TVC nozzle they showed in CGI is actually a Russian style nozzle which has never been found in academic essays or seen as a demonstrator ,actually multiple essays came to a conclusion that raptor-style TVC is the best and should be developed for future aircraft(more thrust loss but by reducing the drag actually improves the high-speed performance,lower RCS,lower heat signature ) ,the TVC nozzle we’ve seen on J-10B comes second (lowest thrust loss ),and the AL-31-style TVC is the worst)
I mean ,if you are talking about possibility without substance,even a raptor-like TVC is more likely than that one,it was under development since 80s ,there’s a video with Chinese president JiangZeMing in it.

Ah ,I was wrong,didn’t see the link up there,sorry
