hehe, very often the secrete is hidden right in front of our eyes.

Hmm. Never thought about the dihedral/anhedral arrangement that way. That’s actually very clever, and is also consistent with the approach they took to reduce specular angles on other dimensions of the plane’s geometry.
Edit: Looks like the Rafale took the same approach.
I am afraid that Rafale is not taking the same approach. Compare them at the right angle and photographing vantage point.
Rafale is close-coped canard, while J-20 is far-coped canard closer to Eurofighter. The two configurations work very differently. I would guess that it would be very difficult/meaningless for Rafale to do the same while maintaining its canard at that vertical position.
At least based on the frontal view from the diagram that was shared it looks like the canards on the opposite end are coplanar with the wing. This geometric relationship may not hold at other angles for the Rafale but seems to for the frontal view. Of course I’m basing it off a diagram, not a photo. Only sharing initial impressions on my part.
I think that diagram was way off on two points:
- Rafale's canard root is vertically on a higher plane than the main wing. This can also be seen on photos of side view. Also can be seen is that Rafale's main wing root entends forward under the canard (see below).
- From no photo the canards are shown canted.
that is a perfect photo to show everything I was trying to say, thanks.Looks like you’re right.
As did the Mikoyan Project 1.44/1.42, which it has been supposed by some, that the J-20 design either was based upon, or copied. Obviously, NOT!!!
And, don’t forget the J-10!

Canards of the J-20 always reminds me of the Naval YF-23 proposal (Canards, all-moving tails).
For me a J-20 v2.0 that looks like it would be extra cool. One of my personal favorites is off-course the tailless X-36.
NATF-23 proposal
X-36
However there should be no dispute from anyone that Chengdu's J-20 is a "clean sheet" design aircraft, with Dr. Song and Yang Wei's heart and genius, "Stealthy" and gorgeous, she's one of a kind.
and all the talk about redesigning this airplane is just that, the basic planform and layout are near perfection, they WON'T mess with it! It does exactly what it was designed to do, and does it in its present configuration, WS-15's will only be gravy on top.
