With the theme of celebrating Dalun's 100th anniversary, windmills and butterflies are the main characters. Through the course, we will learn about windmills and make windmills; we will learn about nectar plants and butterflies, and then fold or cut out butterflies. Afterwards, we will teach windmills and butterfly installation art to cultivate students' The aesthetic feeling inspires students' love for the century-old Dalun school. Finally, through the exhibition of works, it attracts alumni to take photos and check in, spreading joy and happiness, allowing alumni to recall their childhood scenes and retrace their footsteps.
