this wing is pretty diffrent from j-7e double delta. Previous wing was basically a cranked delta, this one is more alike to f-16's design. Almost as if the front part is lerx, then a larger part being the wing itself.
The curved wing design is very pleasing to the eyes. Much better than the double delta design, which was a great improvement aerodynamically over the original single delta design.
Probable provide more lift and a better angle of attack.
