Introduction to Hu Xiantang: Located in the northwest of Penglai Pavilion ancient building complex, it was built in the Ming Dynasty. It faces north and faces south, with a width of 9.13 meters, a depth of 3.73 meters, and a height of 4.45 meters. It is a three-bay, three-beam, hard-topped building. The couplet on the door of the renovated Hu Xiantang is "Go into the deep mountains to cultivate your mind and nature, and come out of the ancient cave to gain enlightenment and become an immortal." There are three statues enshrined in the hall, with Hu Xian in the middle and his two medicine boys beside him. The girl holds Ganoderma lucidum in her hand, and the boy holds a medicine gourd and medical books. On the east wall is "Picture of Collecting Medicine in the Mountains", which was painted by Wang Rulin, a senior painter at the Shandong Provincial Painting Academy.
