There are reasons for the decline of traditional craftsmanship. Students know the beauty of the wooden flower window craftsmanship, and more importantly, practice it. From last semester's study sheet, students were selected to think about the idea of creating a flower window. The students imagined that the window is like the sound hole of a wooden cajon. The ventilation is like sound being conducted through the air. In addition, due to the lack of space, the music classroom needs to be shared with the dance club. Without desks and chairs, the drum can be used as both a musical instrument and a chair, making it easy to store and maneuverable. The wooden box drum (cajon) inherits the Lukang wooden flower window craftsmanship and connects the origin of the drum. It is like opening a window and seeing a different world, including the human rights stories of African Americans, different life backgrounds, and different histories.
