Want to go on a tour of China which includes cormorant fishing on the Li River. National Holiday.

Hi

I want to do a tour of China that includes seeing the cormorant fishing, Kuoni do one but the best dates for the tour menas we will be due to see the fishing on a National holiday (mid autumn festival) on 19th September 2013. Anyone know if we will still get to see the fishing or will this be called off as everyone will be with their families?
