I think what they called 8 x J-8II should be JH-7. The shape of their wings is not delta wing and the wingspan is wider.Satellite images of expansion activities at western airbases. Not sure about the analysis and identification, as it's done by some Indian guy, but the images are nonetheless interesting.
Common J-8 almost retired from PLAAF, only the reconnaissance variant JZ-8 in service by now, but reconnaissance aircrafts seldom show up in pack.
