Chengdu is the capital city of Sichuan Province in southwest of China and the most important transportation hub in southwestern China. Most travelers in China’s southwest pass through this way at some point. The transportation network in Chengdu is very developed, with direct flights to some international cities, direct flights/trains/buses to large domestic cities, and high-speed trains to several popular tourist cities. Exploring is made abundantly easier by China’s vast high-speed rail network – the world’s biggest.
