It is not necessary to travel to other places to learn about the other cultures.

We can learn as much from books, films and the Internet.

To what extent do you agree or disagree？

Some people argue that media is a good approach for know about other cultures. We can surf the internet to any interest of historical cultures and cities, such as documentary film or foreign movies.
Although we can know more about cultures through the media promptly and directly, I prefer to travelling than learn from media.
