It is fast comfortable and convinient to travel by plane. It is also timesaving. Eg, if you want to go to Yuannan, it only take you over three hours by plane but you should spend more than thirty hours to go there by train. The beautiful hostess will take care of you on the plane so you don't need to worry anything. But of course every coin has two sides, traveling by plane sometimes delay by bad weather so you have to wait for a long time in the waiting hall. And you have to shut off your cell phone on the plane. Sometimes you can't enjoy the beautiful scenery.
