Just for full disclosure, what was said is that a J20 was spotted at RiZhao (civilian) airport in Shangdong province.
The key sentence exactly translates is:
‘Don’t know if it coming here is related to the navy’ (I don’t have the exact eyebrow-lift-sideways-glance emoji).
I leave it to each member to decide if the question is rhetorical.
Interesting that the V-tails seem to be huge. For naval aviation, we usually see increased wing areas to increase lift for short take-offs. Why enlarge the V-tails, though?
