The treasure box is located next to the "Diudiudang Forest". It is located directly in front of the Yilan Railway Station. It is now used as a Baiguoshu art space. Designed by the architect Huang Shengyuan, nine giant steel-framed trees with a height of 14 meters show the natural atmosphere with a steel structure and symbolize the Jiuxiong Tree, creating a unique image of the old name of Yilan-Jiuxiong City. Combining the landscaping art with the image of the famous picture book master Jimmy's drawing creation, the Jimmy star train full of innocence and dreams and the retro red brick house with the fruit tree beside it, show a strong artistic atmosphere.
