I heard that you will come to China tourism,I want to tell you,good or bad about by train by plane,let me take from Qingdao to guangzhou to tell you.
By plane will cost you 1200 yuan,if you take the train,you need to spend 550 yuan,however,you will take 25 hours by train,only 2 hours by plane.
You although comfortable,save time by plane,but expensive,though time-consuming,crowded by train,fatigue,but spend less,also can enjoy the scenery.
I hope I can help you,the interpretation of the last wish you a pleasant journey
