American writer O Henry told a story in his novel The Last Leaf: In the ward, a dying patient saw a tree outside the window from his room and fell down one by one in the autumn wind. The patient looked at the rustling leaves in front of him and his health went from bad to worse. She said, "When all the leaves are gone, I will die." When an old painter learned about it, he drew a leaf with green veins with a colored pen and hung it on a branch. The last leaf never fell. Because of the green color in life, the patient miraculously survived.
