Southern poet, Dr. Tseng Kuei-Hai, not only focused on his specialized thoracic medical but also spent his time leading a group of people from Kaohsiung to involve in environmental movement and the result turned out well. With this foundation and love for Taiwan, he went a step further to establish the department of Taiwanese Literature to raise the rate of education of Taiwanese vernacular and to enforce the research for Taiwanese history. Everything described above was expectable. It takes meticulous thoughts of a poet to lead social movement, however, Dr. Tseng Kuei-Hai, converted the same thoughts to the creation of poems from extol the earth, admiring Taiwan and the mood expression in the age of fifties and sixties. Since everything came along with his love, his poems showed up like warm sun and stated the feeling life. In the past few years, Dr. Tseng Kuei-Hai's poems stated from the foundation to fully elaborate Hakka culture. His poet 'Magnolia coco' highly praises Hakka women and 'Defending War at Siia-liou-gen moon building' tells the history of the country. These poems illustrate his infinite vigor and his high aspiration against injustice groups. Dr. Tseng Kuei-Hai does have a clear conscience to be called as a poet with the character of social movement.
