[Callers] Chinese Fan from Square dance

Hi. I'm new to the list, not a caller yet, but wanting to learn more about Contra dance and maybe calling. I've got a friend who is writing a 4x4 contra for me with a Chinese Fan in it. He needs to know how to call the Fan as he can't figure it out from the one video I've found on youtube that has it in it (Three Arches) www.youtube.com/watch?v=Q8c6Xzn3AyE Can you tell me how to call a Chinese Fan? Thanks! claire
