Ten years after graduation, Pei Pei has grown from a small doctor to the deputy chief physician of a large hospital. Like his fathers, he has a seemingly decent job, a stable income, a virtuous wife, and a lovely daughter. When I attended a class reunion, I suddenly felt something when I looked at those faces that were once young and shy, but now they could not hide their sadness and age. There is truly a journey in life that is as beautiful as a dream. When I returned home, I found the four photo albums that she had given me when she was a student. When I looked through them, those pages of photos traveled through time, taking Pei Pei with me, and reliving the dream again.
