The J-10A has around 4 usable BVR stations under the fuselage.. and another four on the wings.
If fuel tanks are carried.. that still give it 4 BVR weapons under the fuselage.. +2 tanks in the inboard plumbed stations.. +2 BVR in stations 3 and 4.. along with 2 WVR at the outer wing stations...
However.. that all depends on whether the stations underneath the fuselage are capable of holding BVR's.. weight and ground clearance being the primary factors.
In case they arent.. the J-10 may use a dual rack on 3 & 4 to carry 4 MRAAM's..and 2 SRAAM's.. not a very potent mix.
The fuselage hardpoints for the J-10 are crucial to offer any competitive ability in A2A combat against the eurocanards.
I agree that it has 4 stations under the fuselage but none able to carry BVR. The frontal are probably going to be used by targetting and IR pods. The back ones are not capable of holding any BVR size weapon without obstructing gear bay doors or ground clearance.
