Nowadays we have an excellent opportunity to travel abroad because most countries are open for us. Let us speculate, if it is true that culture, story, life arrangement of another contry help us to understand our own one.
In my opinion, only travelling to other countries can help you to understand your own deeper and more complex. Firstly, you can know your country from various sides because another country is like a mirror. Secondly, while travelling you will transform your world view and wide outlook, so your relative to place where you live in will change extremely.
However, there are contrary point of view. Some people believe that travelling cannot help you to know a lot about your own country because you can change your mind to negative way, so this fact will prevent you. Also opponents convince that you can just read some books or watch some films about countries abroad instead going there.
To some extent it is right, but I think you have to know about weak and strength sides of something to love it and only traveling, only your own experience can provide you object and colorful view on your country.
Sum up, all of the things we can know just only when we compare and contrast them with others.
