The QBZ family of rifles, both the older bullpup Type 95 and its variants, and the newer Type 191, fire a 5.8 x 42mm round, not the AK 74 ‘poison bullet’.
While I am sure the PLA has tons of 47s, and 74s still in active use, their efforts to modernize have included introduction of and seemingly wide issuance of the QBZ 95 family since roughly the early 2000s, and more recently the Type 191.
Usually when they do publicity videos or images, they like to show off the QBZ family.
I have seen PLA videos of basically an urban combat live fire on static targets.
You get an absurd amount of keyholing at ranges that between 5 to 10 to 20 meters.
Its possible this particular image is from a longer distance static range, but the keyholing problem seems to be quite widespread, irrespective of range.
As has already been said, something is going seriously wrong with either the guns, bullets or both that are being mass produced for around a year now.
