The world is changing.
How to survive in a authoritarian political system?
What to do / not to do ?
This is a simple question with an easy answer.
If you want to live then do as your told. Obey the regime and follow its code. You do not need to join them just follow what they want you to do and you'll be fine.
And why such a life? I don't understand how people allow to power in their country's dictators. Freedom can not be a price for life. For me a sure sign of the presence or absence of dictatorship in the country there is legislation about guns. Only free people have the right to arms.
