This is a real piece of lol.
A random person claims PLA has very little UAVs in service. Then backs up the statement by saying if the PLA had a lot of UAVs then they wouldn't keep the number a secret ...
PLA has more types of UAVs in active service than India has units of UAVs in service just for a comparison of numbers. It would not be a surprise to anyone if PLA currently has more UAVs in service than any other force in the world (including the US). Let's see, the manufacturing and industrial output is greater, the costs are lower, every single component down to the chips are made in China and can be sourced locally (through multiple vendors and not just limited to one or a slight few). Labour costs are lower, energy costs are lower, raw materials China has the most in the world and the largest stockpile of ore and steel among other raw materials required for UAV manufacturing.
Nevermind that China is responsible for the vast majority of global commercial drones. Their development, design, manufacturing. In most cases, also their IP and patents.
They have ability and potential to mass-produce UAV doesn't prove they have a lot of UAV in service. Chinese military industry was keep exporting glide PGM, have you ever seen any glide PGM on PLAAF aircraft?
