Equally timeless are the works contained in the series "The Human Character." Here Lee's tender lens ponders worn but contented adults and bright-eyed children. His famous work "Shepherd Children," in which three barefoot children in tattered clothing smile as they look to the horizon, has been described as the most emotive work in the history of Taiwanese photography.
同樣歷久不衰的是〈光影歲月〉系列，在他充滿人文關懷的溫暖鏡頭下，大人樂天知命，孩童天真爛漫，尤其名作《牧羊童》中的 3 個孩子，打著赤腳、衣衫襤褸，卻帶著笑容望向遠方，被譽為台灣攝影史上最撼動人心的經典之作。
