First off, positing that you want to mobilize the population and organize it to become active supporters of your position, you send out "door to door salesmen" (preferably locals) who patiently work the towns, villages and hamlets.

If that begins to work (your "salesmen" are accepted by the locals), you could add such as comic books and traveling musical and stage companies. Also, at some point, you'd want to add radio stations to the mix and provide the folks with basic receivers.

All this is pretty much basic Mao and those following his organizational approach.
