In my junior year of college, I got to know Sister Lan while working as a tutor. That day, she was wearing a maroon knitted sweater and sunglasses, leaning against a red BMW. Her long hair was flowing in the wind, attracting the attention of students passing by. From afar, I saw her, but I wasn't sure. So I made a phone call. She seemed to have seen me too. While answering the phone, she waved at me with a sweet smile, just like the sunshine in spring. If there is really love at first sight in this world, then the encounter between Sister Lan and me is destined by fate.
