vortex on the J-10

we know that Canard delta causes vortexs toward the vertical stabilizers, yes it does..

the Typhoon has two slats on the sides behind its canard to “channel” it out similar to the Mirage 2000, while the Gripen has a smaller one. The Rafale’s canards are placed closer, thus the vortexs dont have as strong effect.

What about the J-10? Its canards are placed well in front (but not as far as the Typhoon) to cause a vortex to the vertical stabilizer.. is there any piece on the body that channels it out
