Professor Tseng, the president of Jiu-Cheng Cultural Association, acquaints us with Zuoyin Old Castle. In addition, he lets us appreciate the beauty of the Old Houses.

Mrs. Lin is our great helper before we meet Professor Tseng. Were it not for his help, we would lose our way for a long time and never find out the Old Houses that we need. Besides, the first hand information of the Old House that she provides helps our research run smoothly.

All parents had given us, both teachers and students, the best spirit support. There were many outdoor visiting and field-investigations during our research processes. These enthusiastic parents were in charge of driving all the way and learned with us as well. They helped resolve the transportation concerns and share responsibility for students' safety. They were our best backups.

Teacher Huang Shih Wen, a member of Jiu-Cheng Cultural Association, spends all day bringing us to visit the old settlements and temples of Zuoying. His professional analysis benefits us greatly.

Ms. Chien is the principle of our school. She has good accomplishments in manipulating computer. During the process of this research, especially in winter vacation, she not only came to school to encourage us frequently, but also provided us with a lot of snacks and meals, which made us more energetic proceeding our project. Furthermore, she had checked our web site for valid connection and corrected wrong words every day. What she did for us was really touching.
