One cold winter night in Shanghai, I was walking home at one in the morning after long tiring work. I was having trouble with my job in the bank. As I walked, I thought seriously about giving up living there. City life had become too much for me.
As I walked down empty streets, I felt very small and cold. I began running, both to keep warm and to keep away any possible danger. Very few people were still out except a few sad-looking homeless people under blankets（毛毯）.
Suddenly, I heard a sound behind me. I turned quickly, all I saw was a shining streetlight. Still, the noise had made me nervous, so I started to run faster. When I reached home, I realized what the noise had been. It had been my wallet falling to the sidewalk.
Now I wasn't cold or tired anymore. I ran back to where I'd heard the noise. Although I searched carefully for fifteen minutes, my wallet was nowhere to be found.
Just as I was about to give up the search, I heard the garbage truck（垃圾车）come to me. When a voice called from the inside, “Alisa Chen?” I thought I was dreaming. How could this man know my name? The door opened, and out jumped a small red-haired man “Is this what you’re looking for?”he asked, holding up a small square shape.
It was nearly 3 a. m. by the time I got into bed. But I had got my wallet back. I also had got back some enjoyment of city life. I realized that the city couldn't be a bad place as long as people were willing to help each other.
