In order to promote the concept of sustainability and combine it with local culture, the 2025 Yunlin Sustainable Micro Lantern Festival would be on display from February 10 to February 23. This time, the Yunlin County Environmental Protection Bureau and the team of teacher Chen Fangru from the Department of Visual Communication Design of the National Yunlin University of Science and Technology created the lighting installation works "Bamboo Mountain Sound" and "Bamboo Wave Sound" that combine environmental protection and art. The two works take "Mountain" and "Sea" as their themes, showing the natural charm of Yunlin and the innovative design of waste reuse, conveying the profound meaning of "Mountain and Sea Regeneration: The Resonance of Land Sustainability".
