　　It is the end of the year. SME Association of Youth Volunteer organized a volunteer teaching tour to BeiShenShu Hope Primary School in Tongzhou District as scheduled. After two hours of bumpy ride, volunteers arrived at our destination - BeiShenShu Hope Primary School. Volunteers expressed that this volunteer teaching experience would be their own permanent wealth, and they would continue to support the volunteer activities.
