The Dehua Girls' Hostel was opened for female workers at Dapinglin, Xindian, by the Catholic Divine Word Missionaries in the 1960s, when the neighborhood had a large number of factories, where young girls coming from around Taiwan were widely hired and dormitories housing them became an immediate issue. The hostel was named after Father Edward J. Wojniak, SVD (1909-1983, also pronounced as Father Wan Dehua in Chinese), the Parish Priest of the Catholic Divine Word Missionaries in charge of the Holy Trinity Church in Dapinglin. Father Wojniak, a Polish-American, who was responsible for the planning and construction of the dormitory, had served in China's Henan Province, from where he was forced out in the 1940s by the Communist government and he had to return to the United States. In the 1960s, as a volunteer to Taiwan, Father Wojniak built the Holy Trinity Church in Dapinglin, and later on he was involved in other works in the area, where the Dehua Girls' Hostel became the most highlighted social service achievement. The idea of the girls' hostel originated in 1965 and, the following year, for the fund-raising campaign for the large-sum construction cost, Father Wojniak spent months in Europe and the U.S.; Madame Chiang, Soong May-ling, was invited to lead the campaign as honorary president of the committee calling for international engagement and assistance. The hostel began running in 1968 when its phase 1 works were completed with much appraisal. As more buildings were completed in different stages for young working girls from a over Taiwan, the program saw changes in both subjective and objective conditions, and eventually, the 20-year-old Dehua Girls' Hostel was forced to stop running officially in 1988. This is a case study on the establishment and development of the girls' hostel, an example of the Catholic Church dedicated to social services.
