_{Today, I went to super market and bought some food and fruits, when I came to checkout, I said:” give me a large shopping bag”, “0.5yuan” cashier told me. To be honestly, it is a long time for me no shopping in supermarket. I didn’t note a normal polybag can be 0.5yuan per pc. It should be one way to courage customer to use their own bag for shopping.}

_{Looked back the people line pending payment, they almost didn’t bring their own bag, all will buy polybag from supermarket. So I think public awareness should be emphasized to protect environment.}

_{We’d better to bring a cotton bag from next time when I go shopping.}
