Hello
We are planning to visit china on September-October.
We want to get to Guilin from Kunming around September 30th. When I try to search for train around that date I see that the calender marks X on all the dates between Sep 20th - Oct10th. Does it mean there are no trains on those dates? Or the delivery is not working these days? Or maybe everything is fully booked in these days? Does it have anything to do with the holiday that takes place on the beginning of October?

Thanks
Itamar
