It’s no secret that North Korea is very strict about what visitors can do and what they can bring, but that hasn’t stopped many from smuggling content in and out. That is becoming more difficult, however, as the nation grows more paranoid about security amidst its push for tourists. Bringing so much as a single paperback book could get you extra scrutiny from officials.

Trying to buy something from an unapproved vendor, for example, is a no-no. So is talking to strangers, snapping wayward pictures, saying anything in personal phone calls that may be considered critical or negative of the nation, and more.
