Generally, I think of travel as an opportunity to learn about culture and language, and to see--first hand-- the wonderful diversity of environments around the world. 

When I travel, I try not to stay in expensive hotels; rather, I like to stay in hostels (cheap hotels with few amenities, but where you can also meet interesting people), leave early in the morning, and walk or bike ride around the region I am visiting. This way, I feel I get a more authentic travelling experience, and develop a deeper understanding of the country or city I visit.

Most expensive hotels are the same everywhere in the world, so you might as well stay in one in your own city! :)

Some parts of the identity of each people are based on their living place. The place we live in gave us a lot. However, we are also bounded by our living place. People sometimes want to escapse from the bounding place and want to know themselves and change themselves by the influence of different culture by traveling.

The word "more" in the first sentence should be "one".

It is good to travel, because more can learn lots of things from it both physically and spiritually. Firstly,  when one travels, that means he leaves his home, he has to depends on himself and take care of himself. In a lot of times that experience could be very tough, but after one live with it, the person of course will be stronger. Secondly, by travelling, one could learn more knowledge of other places, different cultures, and the more one learn, the deeper he can understand the world and the life.

I personally feel travel can understand the different ground or exotic culture
