　　 Not only do we cost less when we travel by train, but we can also see much good scenery. Take the trip from Beijing to Guangzhou for example, if we go there by train, it costs us about 271 yuan, and we will spent about 24 hours on the travel. Besides, it is very crowed, and we may not have a good rest. But we can see much good scenery along the way.
　　 If we go there by air, it only takes us two hours, and it costs at least 900 yuan. It”s also very fast and comfortable, and we will have a good rest as well. On the contrary, we will miss much beautiful scenery.
　　 However, different people like different ways of traveling. People will choose the best way which is suitable for them to travel.
