To allow teachers, students, and the general public to explore the mysteries of nature on campus, teacher Lu Wei-Yuan from the General Studies Center of Chung Cheng University spent three years collecting hundreds of photos and more than 130 biological data on birds, plants, and amphibians to develop the "Zhongzheng Ecological APP". The APP not only includes birds and frogs, but also includes navigation functions, and even the unique "Zhuluo tree frog" in the south of Yunnan.
