The subject of our study is our hom etown - Guotianzi Area. Therefore, we interviewed a senior citizen, Teacher Tsai, as he is very familiar with the area. In order to discover issues in our community environment, we interviewed Chengsi Neighborhood Chief, Ms. Shiue. In addition, to understand the story of the yurts, it is necessary to interview the founder of the English Village, Principal Weng, as the yurts were left from the village. Lastly, we visited the manager of Dream Mall to understand how the department store industries deal with their trash.
