The volunteering spirit has spread among the Chinese people in recent years, especially among young people.

Volunteering is of tremendous benefits to both those in need and society. Take the Wenchuan Earthquake as an example. Hundreds of thousands of volunteers play an active role in Wenchuan quake-hit areas. And they contribute daily necessaries, offer medical help and psychological help to the disaster relief work.

Besides, volunteering would be beneficial to the volunteers themselves~ Getting involved in volunteering, volunteers will be exposed to a new environment, and they can learn how to work well in a team, how to improve their interpersonal skills and organizational skills, all of which are critical for their professional growth.

As a college student, I sincerely hope that everyone would join the volunteering work. It is not only good to our society, but also a chance for us to grow and to learn.
