Didn't I say I'm not saying it is? I said at glance it looked like a Dark Sword.
Well, Anjian and J-20 have similarities and difference. They're both canard stealth fighters, to begin with, but the Anjian lacks the double lerxes that characterize the J-20, and the J-20 has twin tailbooms the Anjian lacks. Moreover, the Anjian seems to have wider wings than the J-20, and well, the pilot pod is obvious with the J-20.
In either case, this is just a tutorial on Anjian vs J-20. IMO, the Anjian has too small a weapons bay capacity to perform for the J-20 as a "loyal wingman"-type missile escort, but it also lacks the lerxes and aerodynamic optimizations for the Anjian to function as cheap dogfight cover. The only superiority of the Anjian vs the J-20 would be in terms of cost, as the Anjian is an unmanned drone and doesn't involve putting a pilot in.
