What's that? Is it legal tender? Where is this wording you're talking about?
Just regular 1RMB notes upon which someone has written FLG slogans in ballpoint pen. I've run across them too.
This one went a bit further. It was actually printed on in big, red letters. Mrs. AJR translated it for me.
I'm not sure how safe it is to write the words together, so I'll say it said 'tr**h', 'com***sion' and 'for****ance'.
