Aunt Wu was actually a student who my father used to teach in a rural middle school. His surname was Li. His family lived in a village far from our county. Since I was sensible, I knew that she had a very good relationship with our family, but I never figured out why she was so good. I just remember that she often went to my house to play since she was a child. It was quite normal for her to eat. Sometimes when my father was on a business trip, she even came to be a companion for her mother. Later, she went to the pre-teaching class of primary school in our town. Because of her reasons, I went directly from the kindergarten middle class to the pre-school class and became her student.Since then, I called her Teacher Li, of course she also called my father Teacher Huang. But later, my father introduced Teacher Li to his cousin, which is my fifth uncle. She became my fifth cousin. My uncle was in his 20s and did business in a coal-producing city in another place. He basically settled his home in another place. Teacher Li later followed his fifth uncle to another place. It seemed that he had run a kindergarten in that city. So in the fourth grade of elementary school, Teacher Li disappeared from my life until I went home during the Chinese New Year in 2006. It was almost 15 years later that I saw her again.
