By going to Tainan Qiaotou Beach Park for beach cleaning activities, students were able to reflect on the causes of marine pollution during the service process and participate in the cleaning of the coastal environment by themselves. The students were also led to the Taijiang Fishing Paradise for a professional tour to increase their knowledge of the ecology of the coastal estuaries, and to get closer to nature to further understand the story of the ecological environment of Tainan's capital city.
