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.
