Back in the 1970s, D.C. Chen, who had worked as a janitor to pay his way through Tamkang University, was at Chunghwa Chemical Industrial Works, which produced sulfuric acid. Chen moved through the departments of general affairs, sales and manufacturing to become a high-ranking executive there. Also a manager at the recently founded Baoyuan Chemicals, he was making a good income.
時光倒帶回 1970 年代，陳定川還在製造硫酸的中華化工任職，當時他已從工友一路半工半讀到淡江大學國貿系畢業，也因表現優異，從總務、業務、廠務爬升到最高階的專業經理人，還兼任新成立的寶源化工經理，收入頗為優渥。
