They had been taken, you see, 30-some years ago by Huang's father, Huang Yung-an (also a doctor), and the children pictured were the younger Huang and his sisters Na-na and Shun-shun. Somehow the photos had been misplaced after their father's death and wound up in the used book stall.
原來拍照的正是他的父親黃永安，也是一位內科醫師；照片上的小主角們，是卅多年前的他和妹妹黃娜娜、黃順順；這批照片，則是父親生前親手放大留存的傑作，很可能是被整理故宅的歐巴桑，夾在廢紙堆裡賣了酒干，又輾轉流到舊書攤，才曝了光。
