Ginkgo Leaves and a Butterfly

I love these ginkgo leaves. These are the only trees inside our school that make me feel that there is fall in Suzhou, China. All the trees here in our school remain green throughout the year except these ginkgo trees. I feel sad when they sweep these leaves away. I don't really think of them as rubbish in fact I think that they make the place beautiful by spreading gold in the ground.
