certainly not nearly that many. there's 3 divisions right now, not 5, if i am not mistaken.
Even so, transporting even a light infantry division by air, using only unprepared runways, means basically just y8/9, il76 and y20 could carry various vehicles, trailers, large palletes and other supplies. Alternative is that various mi17 and z8 are also used for small vehicles and palletes but their range means they can't really do it within 24 hours ANYWHERE in china.
Given how a US infantry brigade (less than half the size of division) has some 4000 vehicles/trailers, Chinese unit one can't be that far behind.
Hypothetical available 20 plane y20, 20 il76, 100 y8/9 force (quite a bit more numerous than today's. unrealistic to expect more than 70-80% of fleet to be available) might be able to do an average of two flights within those 24 hours.
I'd say closer to half a division, or maybe one division if we're talking mostly just paratroops with little to no supplies.
