Before the Spring Festival, I thought about doing something meaningfully. Suddenly, I remembered that there was a lot of primary school students putting up small shops and sell red bags on the street last Spring Festival. Wanting to have a try, so I begged my father to support him. He bought some lovely red bags and small toy. For the first time in my life I begin to sell things at the gate of the park. This experience of selling taught me the secret of communicating strangers, and I understood what hard it is for my parents to make money.
