Air travl has two advantags ovr train travl. First, it can sav much tim.W can fly from Bijing to Guangzhou jusi in two hours, but by train, w hav to spnd 24 hours or mor. Scond, air travl is mor comfortabl, bcaus th plan flis so smoot qly that w can rst wll during th trip, whil th train is crowdd somtims and passngrs hav to sit for a long tim, which maks thm tird. But train travl also has its advantags. For xampl, travling by train costs only 250 yuan whil travling by air will cost 900 yuan.Bsids this, outsid of th train＇s windows, w can njoy th viws of many big citis, such as Zhngzhou, Wuhan,ad Changsha.

So I think diffrnt popl lik diffrnt ways of travling.
