In Zhu Ziqing's essay "Back View,""I was really too smart at that time"(the fourth sentence of the fifth paragraph), the word "too smart" should be understood as "too smart." This sentence comes from the fifth paragraph of Zhu Ziqing's prose,"Back View". The original text is as follows: I was so smart that even my father thought it was wrong. I still remember that day when my father and I went to pay a New Year visit, we saw a boy carrying a bag of books and asking an old man for advice. I thought to myself, how good would it be if I could ask this old man a question! So I took the initiative to walk over to the old man and said,"Grandpa, can I ask you a question?" The old man was very happy and waved his hand again and again. I was so smart that even my father thought it was wrong.
