If you want to see the original screencap of the announcement by AVIC, it's in this thread.
Why is it ridiculous?
The carrier variant of FC-31 is obviously going to be a new fighter, and by the sounds of it the PLAN only committed to a design for its carrier based 5th gen fighter a few years ago. It's not like the FC-31 was designed from the outset to be a carrier based fighter and the PLA never committed to it themselves until the PLAN did either.
What is more important is how long the development of the J-XY/J-35 takes. I have a feeling the years of flight testing the two FC-31 v1 and v2 prototypes will have some benefit.
