I know historically ROCMND like to compare themselves to Israel, so for them changing their own mindset and thinking of themself as the Iran would be a big leap and frankly I don't think it will happen so they won't learn anything from this war. But suppose we assume they are pragmatic for a change and actually goes for mosaic warfare - it is after all also the direction US wants to push them in.
So if they become more IRGC-like, how would PLA deal with flying mopeds and all the other innovations seen in Ukraine? For organic SHORAD that's part of a combined arms brigade I don't think we have to worry, they are already on the case. Recall in last year's parade this vehicle the FK-3000 was demonstrated:

Instead of this one:

Type 625.
Guancha guys talked about this afterwards and they said this is no coincidence. FK-3000 is starting to phase out Type 625 despite it being pretty new precisely because of what they are seeing in Ukraine. FK-3000 with its 35mm cannon can fire AHEAD rounds and being able to carry a huge number of small missiles vs four MANPAD missiles are all so that FK-3000 is better at dealing with small targets like FPV, Lancet, Switchblade etc. So PLA is certainly learning the lessons from Ukraine when it comes to SHORAD.
Question that I don't know the answer to is weather there's preparation done yet for defending fixed installations against small drone targets like Geran-2/Shahed 136/LUCAS/Chien Hsiang, and potentially large swarms of them at a time.
It could very well be that PLA has thought about this and done the work already, and some point in the future when we see a CCTV segments on some kind of installation we see in the carpark two LY-1 lasers parked and connected to EV fast chargers.
