I agree with that everyone should go aboard that will make them learn and understand a variety of cultures by themselves. They can also present our culture to make others know and understand. On the other hand, people who not have a chance to go aboard does not mean they will not have the opportunity to learn and understand the other cultures but they are also able to learn without go abroad. They can learn from books or listen to story about experiences from friends who go aboard or they can go hang out with friends who have different nationalities, languages and ages to learn by themselves although they did not go overseas.
