Understand the city by visiting one or more of its many museums and galleries, which include art, history and cultural exhibits.
Enjoy the nature available even in this urban area. Numerous parks make this easy.
Research your travel options online before you book your tickets.
Book your travel tickets in person to avoid any problems. You can book them at the train station or through a travel agent or hotel staff.
Pack snacks. The train should have a restaurant car (usually the tenth car) which serves local food, but this is a long trip and having your own snacks is wise.
Pick up a phrase book since train staff do not always speak English.
Take a bus or taxi to the Guangzhou train station. Be sure to arrive early.
Make yourself comfortable. No matter what type of seats you get, get as comfortable as possible for the trip ahead of you.
Pay attention to the landscape. It will change significantly during the trip, so enjoy the chance to experience the changes.
