Me and my friend are planning to China travel next year.well train travel in China is an interesting experience, with the world's fastest train (guangzhou to wuhan), the word's highest train (in tibet) and the world's oldest working train (from Tonglio to Baotou in the north of China). Now travelling in China by train is not always easy.You can do a Hong Kong to Beijing Train trip, and buy those tickets online. But to be honest with you, most of that journey is pretty boring. The best part of it is going through northern Guangdong and Southern Hunan provinces.ChinaTour.com is a reliable China Travel Agency based in USA, which has specialized in inbound China travel for decades.
