This is very bad. I ordered it to Ctrip (+ subsequent agents) more than a month in advance, but there was no seat (I must have not placed the order, waiting for group buying or something)! The follow-up service of Ctrip customer service is not active. I suggest that if you want to play, you can find the official website to order it yourself. Ctrip has many good services, but this order is really bad! And when it comes to being bad, it looks like a rogue, as if you can do nothing to me.
