Okay. Sure it's fine to visit North Korea. But you must not:
1. Bring a Cellphone
2. Bring a laptop
3. Bring a camera
4. Tell anyone about the place if you're not a journalist or something.
5. State an opinion.
6. Ask questions about their beliefs.
7. Never defy them (like saying "there is a market, dumbass.")
8. Always say their beliefs are true.
9. And don't EVER say Kim-il Sung isn't immortal
