After he completed his military service in 1966, he got a job as a medical photographer at a U.S. Navy research institute in Taipei. During his twelve years there, he learned many photographic and developing techniques. In his free time he traveled around shooting pictures of people and places he found interesting, and he also got to know Teng Nan-kuang, whose influence resulted in a greater breadth and freedom in his work.
一九六六年他退役之後，經朋友介紹與推薦，擔任「美國海軍第二醫學研究所」的醫學攝影師，在那十二年的職業崗位上，他不但專心觸及了新聞紀錄、顯微攝影、醫學圖表、幻燈製作、暗房特效等技術，也利用閒暇四處獵影，拍攝他所喜愛的人物風情。
