You can take a bus, about 8 hours, which is relatively long.
There is no need to buy tickets in advance because the ticket source is not tight, but September is the peak season, so it is recommended to ask at the station in advance. The price is 160.
If you rent a car, the travel agency can arrange it for you. The price is not too much water, it has been very stable. If you rent a car, 800, carpool 150.
Above, I hope I can help you.
