The purple coat at the back is a big purple sweater made by Zhu Ziqing's father. This purple freshman was made by Zhu Ziqing's father because he was worried that he would be cold in the cold winter. This is followed by a reminiscence essay written by modern writer Zhu Ziqing at 1925. This article tells the story that the author left Nanjing for Peking University. His father sent him to pukou railway station to take care of him and buy him oranges. What impressed me the most was the back of my father climbing up and down the platform when he bought him oranges. With simple words, the author expresses his father's love for his children deeply, delicately and sincerely, and shows his care and love from ordinary events.
