As we all know,December 5th is international Volunteers Day.And China now has 4.5 million registered volunteers who have provided more than 4.5 billion hours of volunteer work.Why so many people would like to spend free time volunteering?Here are my opinions. Firstly,in my view,the most important reason which helps poor people is that make more people be lucky.Just as the saying goes,to help others makes yourself happier.When you try your best to solve some people's problem,you may feel full of happiness or satisfy.Pain more,gain more. Secondly,during the volunteering period,we can make many friends who are from different places and have different characters.I am sure we can learn many experiences about how to deal with people.Nodoubtly,it is more useful than what we can learn in campus. Even though the number of volunteers is increasing,the number of needed people is increaing more quikly.So join us and make better world.
