Answer:
According to Mao's actions and behaviors opposition to the government should be fought and censured. Thus, for them to be effective they should go on the international media platforms to inform their cause, because inside china they would be defeated.
Step-by-step explanation:
The reasons backing this answer are that Mao was a totalitarian suppressor that fought opposition with force and censorship. The first example is the Tibetans, the second is the GDM workers. Now, to be effective any opposition group or movement should look for help abroad to support their cause as the CCP has almost total control inside china.
