No. 47 Wutong Road is a dusty old house with two floors and one floor. It has a small yard and a thick and strong sycamore tree in the corner of the yard. My name is Fang Yi. This is my home. I have my grandparents at home. Grandpa was a scavenger, and there were always piles of various things in the yard that he had picked up. They were all as dusty as this little house. I can only see my grandfather after evening classes. He is sitting under a tree, humming a little tune, and carefully cleaning the rags he has picked up. Grandma worked in the cafeteria of the middle school next to me, which was also a dusty elementary school. There were only two people in the entire cafeteria, Grandma and Mrs. Ah Chun across the street. Every time it was time to eat, grandma would lean on the door railing of the cafeteria with a smile and call me: "One by one, one by one." I would be the first among the children after school to rush to grandma and let her rub my hair carefully.
