Dear John,
I’m very glad to receive your letter and knowing that you are very much interested in what volunteers do in Nanjing, As a member of the Nanjing Volunteers Association, I can tell you a lot.
Could you please tell me what you do as volunteers in the US? Hope to hear from you soon.
Best wishes,

NJVA is a non-profit social organization set up about 20 years ago. It is made up of people who are willing to do things beneficial to society and for those in great need of help. Anyone can sign up for the membership on its website www.njzyz.com.cn.
As student volunteers, we helped clean the streets in the holidays, and planted trees in local parks last year. All our efforts have paid off when the city is taking on a new look. We also donated money, books and clothes to children from poor families.
I myself have learnt a lot in these activities.……
