Introduction to the Eight Immortals Archway: There are two archways with four pillars and single eaves at the front and rear of the entrance to the Eight Immortals Crossing the Sea. One is "Eight Immortals Crossing the Sea" and the other is "Yunwai Xiandu". Both are handwritten by the great writer Su Dongpo of the Northern Song Dynasty. Su Dongpo once served in Dengzhou. Although he only served as an official for five days, he did good deeds that the local people will never forget for generations. He also left many beautiful words and poems, which added color to the landscape of Penglai.
