Besides stealing intellectual property and propagandizing on social media sites , what else are the Red Chinese up to?

Eating Chinese food.

the whole idea of Marxist socialism and total sharing of all world assets , is the reason they do not see stealing intellectual property ... just because one man works harder creates a product does not give him the rights to his invention - creation.  

thus they really do not see what we see as theft - the bad machine does not know it is a bad machine 

the fact socialism does not in the long run benefit the masses and there is no effective growth of assets they are just trying to gain more power over the world -- as in many wars to take products others create to feed their armies 

Probably doing laundry

Launching biological attacks on the world.
