Dongshi Town, where Bao Dao Company is located, lies in northeastern Taichung County, between Central Mountain Range and Taichung basin. In its early days, Dongshi was abounded in camphor timber. Therefore, Dongshi had a golden age of camphor oil production. Bao Dao had been making camphor oil since the Japanese colonization era and the family business had taken place for over a hundred years. Up to this moment, the company still insists in producing camphor oil by hand for its outstanding quality.
