Last week I paid a visit of my friend Li Lei. His mother sincerely asked me to stay for lunch with them, and I agree. There were only three people for lunch all altogether. However, my friend’s mother prepared eight dish and we couldn’t finish the food at all. As the result, the food that was not finished thrown away in the end. When I went back home I saw some homeless people beg in the street, where reminded me of the wasted food. I felt really sad. What I wish that no food would be wasted from now on! In this way, nobody on the earth will be hunger.
