Recently, the increasing of shared bikes have made our lives more convenient. However, my classmates and I often noticed some shared bikes place messily everywhere. We felt upset but decided to make a change to the uncivilized behavior. On Saturday morning, we gather outside the subway station. First, we began with those messy shared bikes and tried to put them in to order. People passing by appreciated that we did. Seen the bikes in rows on the pavement, we felt excited. Then, in order to encourage people's civilized behavior, we put up a largely poster saying “Please Be Civilized While Using A Shared Bike”. Of course, we drew much attention from the passer-by. Hopefully our actions will make difference.
