Monkey King has deleted his Weibo post.
In the meantime, there's also @052D成都舰 on Weibo who declared
at about the same time the posts above came out, alongside this guy from Bilibili (profile name redacted for obvious reasons, and his post has also been deleted):

Translation:
On one hand, I don't know who this Bilibili guy is (haven't heard of this guy until today), but if his claim at the start of the post (about his activities earlier today, 1st bolded phrase) is factual, then he's probably related to/inside the system(?)
However, I'm not sure what he meant by "skipped the prototype phase" (2nd bolded phrase). Perhaps he's referring to the technological demonstrator/verification prototype stage (of which the J-20 did go through between 2011 and 2014 with those "200X" units), of which the J-36 didn't go through?
Of course, the above claim of his depends on him being entirely factual/honest.
On the other hand, we do know the @052D成都舰 guy on Weibo has a reliable reputation, albeit his wording is rather vague and open to interpretation.
