you can find something ,which you might be ignorance during the routine life
you can also make friends ,who are like-minded
broaden your horizons ,which might add the edge of the competition in the future
demerits
the cost of traveling might be high for some families ,which might be a grave burden
it's difficult for someone to adopt the environment,especially who are weak in the foreign language
impression
Life is so short, the scenery along the way is always fleeting.In this short time, we should live for ourselves, should enjoy the beauty of life.As a saying goes,the today you squandered is the tomorrow crazily craved by people who are dead yesterday and the current time you abhor will the used time you can never back in the future.So take advantage of the time to see the outside world, do not spare regret life
