Eos, A meeting, such as a celebration meeting for achievements gained. It seems that is a custom, like that of hostesses, used to dress the same uniform, and the sash might just say "Celebration Meeting" -- for example, the sashes of the two girls in the first pic of this thread said: Songji Mainboard; because they were in a computer expo in China, the sashes actually have become the ad banner of the manufacturer Songji! Why did they line up? They have to meet the demand of their boss! LOL! Who are these people? I think Nick-Fun has indicated: they are in a communist nation and because they are dressed in this way, so they might be corrupt communists -- that is, they have become the captives of capitalism.
