In the afternoon of Oct 14, some classmates and I went to Sishang Village and took an interview about local environmental protection activities. My first impression of the village was clean and tidy. The sideway of streets was full of trees and flowers. It was hard to believe that you are in a rural area. Entering the villagers committees, we found two sixty-year old grandmas giving packages of plastic bags to an aunt, who carried a spring scale in the hand. The aunt said, "9 kg in all." Then, she recorded the number on a notebook and gave three bags of washing powder to them. After the aunt finished her work, we began our interview.
