Since 1968, when Hsu opened the Chang-an Advertising Company, and 1969, when Hsu began a twelve-year stint as a teacher of photography at Ming-chuan Women's College of Commerce, and 1972, when he began serving as a columnist for Photography Magazine and China Photography, Hsu has had little time for his photography. This fact makes his earlier photos all the more precious.
一九六八年，徐清波為維生計開設「長安廣告公司」，六九年到銘傳商專商業設計科教了十二年的攝影學與廣告攝影，七二年之後，長期為「攝影雜誌」、「中華攝影」寫評論，並經常為各地攝影會做講評與顧問，拍照的時間反而減少了，也愈顯得其早年作品之珍貴。
