This is new to me. I did not know there are exceptions.
UN says: (乙)保障国家安全或公共秩序,或公共卫生或道德。
This means that you might have to pay for what you have said if you are believed to be in violation of what you can say within a country. No wonder every one is daring to say anything about a country that they don’t reside in. A real freedom is not in your motherland but in a foreignland?
