Traveling to Xian during the Golden Week, any advise please?

It's true because many Chinese tourists go out to travel during National Day Holiday. The tourist attractions will be very crowded. If you already arranged your itinerary, you should do your best to book round-trip train and airtickets as early as you can. Sometimes, you need to take long distance bus. Then you should buy the tickets from the long distance bus stations as early as you can. There are fewer bus stations that support on-line ticket sales. Therefore, you need to buy it at the scene. Sometimes the hotel you stay at may help you book the tickets. When you visit the attractions, you'd better take care of your valuables very well because there are thieves.
