I think we now have a full picture of how the J-20's vortex generation system works. From the looks of it the vortex generators work in stages, with each stage progressing at a greater AoA. The first stage is the vortices formed by the LERXes. The second is the vortices formed from the LERXes in conjunction with those formed by the dogtooth created from the leading edge slats dropping. The third is the first two strengthened by the camber of the LERXes in conjunction with the canard downwash. The last is all prior three plus vortical flow formed over the centerline fuselage from the fore body camber over the inlets. The first three work together to form an ever expanding low pressure zone over the wings that gradually encompasses their whole area, while the last one forms a lower pressure area that encompasses the whole top side of the plane including the centerline fuselage and, from the looks of it at least, the canards.

Not to be let down by the J10 TVC they pulled some Gs there
But sorry to say J10 TVC stole the show at Zhuhai 2018

In airshow performance, it did indeed. But the real achievement would still go to the J-20 for being a VLO fighter with internal bays pulling those turns with minimal canard deflection, no afterburner, and initial "underpowered" engines. I think J-20 still steals the show as nice as a TVC J-10 pulling cobra and various impressive maneuvers is for all of us.
By the way, in a news conference at the Airshow one journalists asked Yang Wei, "Will the J10B's engine (referring to the TVC engine) be used on the J20 in the future?"
Yang answered:"Your question is will it be used, how do you know it hasn't already been used (on the J20)?"
