This day's activity was led by the head of the Residential Services Team, Mr. Wang Ruichang, and the teacher of the 4Shang1A course, Mr. Chang Chi-rong, who led the students of the Multi-Service Learning Course in the class to participate together. The content of the activity was based on the fishery industry in the Qigu Lagoon. We invited a local fisherman, Mr. Li Yuezhong, to come and share his story with the students, and led the students in frog costumes to actually enter the fish farms to operate the trammel nets and observe the production of the hand-throwing nets, so as to guide the students in reflecting on the interrelationships between the fishery resources and human beings, and to explore how human beings can protect the fishery resources.
