Personally I would take most articles from Zhonghua and Tiexue with a grain of salt. Not that there are not high quality articles (like the one on tiexue which leaked the first J-20 picture) but the professionalism on those two forums are far lower than those of CD and Feiyang.
This article is on more than one website, I don't know from where it originated. It seems realistic to me, what I am asking is if there are any red flags in the text. I can't read Chinese so I cannot tell.
