It is easy. Train, bus and flight are all available. But i think the most cheap and easy way is the take a train. The price is about 340 yuan for hard sleeper. It will cost you about 500yuan to take a long-distance bus and to be honest, soft sleeper is much more comfortable than long-distance bus as it may need about 20 hours. You can also choose to take a flight if you have tight in time. As your reference!
