What kind of thing is a souvenir and what is a publicity material?
Propaganda, in fact, the concept is very vague......For example, you go to the Imperial Palace, on the ticket, there may be some other attractions in Beijing introduction, that nature is a little publicity.
For example, when you go to the Great Wall, when you're done, he'll send you a T-shirt that says, "I'm going to the Great Wall."
Souvenirs, in fact, are local specialties, clothing, decorations, these things.
