(Secret extra text: Xiao Xiao's diary said: "I really shouldn't skip a grade. I shouldn't be in the same school as my eldest sister. I shouldn't let others know that Qin Yiyi is my eldest sister in the same school. She became famous for the nth time today. She still failed to pass any of the midterm exams this time. This is no longer news. She is famous because of her Chinese, not because she only scored nine points, but because she wrote an essay titled "Mom, "You gave me all your love", but the essay topic this time was clearly about describing father's love. Even so, she actually wrote a strange story about herself and a stray cat. I asked her what happened, and she asked me very excitedly, "Isn't it very good!" I couldn't believe it, and for the first time, I began to doubt my eldest sister's IQ!
