Guys, allow me, a Chinese citizen, to clear some cloud down here, before some wrongly interpret became some "Yeah, I know that..." some kind of 'common knowledge'.
First, CCP looks for EXTRME nationalism, but never "chest thumping" normal nationism. In order not to make our beloved mods nervious, put it simple: You write a fiction novel (over internet) that in WWIII China kick a*s, you DO NOT get throw into jail for charge of Nazism. Did people live in canada, norway, iceland, brazil... get "chest thumping" by the peaceful govt because they exaggerate their own nation's military power in some fiction? I guess not. Chinese govt and Chinese ppl are just as normal as yours, please don't predict stuff like the "experts" do. (Which you guys already know how off those "experts" are)
Second, the funny thing is, that pic is a direct snapshot from a Chinese military magzine 《兵工科技》's back cover. You can see the bar code and price label if you read Chinese. This magzine, like all the other military magzine in China, is licensed by respective authority (which do the "censors" job). I guess if Jane's defence weekly have a back cover showing the concept of F-35 dropping JDAM blow some warship, nobody would say "this is the evidence that USA is intend to go to war with Russia!"
Last, guys, you know better J-20 is an airsupiority fighter instead of a fighter-bomber. The author of this pic is just a "painter", a person who knows drawing but not necessary to be military fans. The eiditor calls him "we need a fancy J-20 pic for this issue's back cover." and you get your fancy back cover.
And here's the fun part in my own prediction: A painter, got the rough specs of the J-20, he need something else to make his pic "alive". so he baidu (google of China) some warships, get the aspects, and draw all the stuff in one pic. Be it a japanise destoryer or usa naval base, it's "job done" as long as it is not J-20 bombing PLAN 054A.
Guys, just treat China and Chinese as normal country and normal people.
