Biwuxuan is located in the north of Taohuatan, also known as Shanguangtan Cinema, commonly known as the Four Sides Hall. Xuansancha, facing south, covers an area of about 1.51 square meters. Its name comes from the sentence of Du Fu, a famous poet in the Tang Dynasty, that "the fragrant rice pecks at the parrot's grains, and the old phoenix branches are green and green". Osmanthus fragrans and winter jasmine are planted on the east side of the porch, and plantain and paulownia are planted on the west side. The platform in front of the porch is paved with stone slabs. There are two hundred-year-old pagodas in the east and west, surrounded by stone fences in Lintan, and the scenery of Nanshan is unobstructed. The courtyard behind the porch is covered with moss, and the leaves of two century-old osmanthus trees are thick and green. The porch has built-in Qing mahogany tables and chairs, a few meters long, and a wooden portrait of the "Three Clear Pictures" of pine and bamboo stone hanging on the hall board of Zhongyan Gate, which is 1.67 meters high and 1.36 meters wide, and famous paintings and calligraphy are also hung on the powder walls on both sides. There are six plaques in Biwu Xuan, such as "Huqiao Changchun", "Sit quietly and enjoy yourself", "Mountain Light and Pond Shadow", "Sit quietly and enjoy yourself", "Biwu Xuan" and "Huqiao Changchun". On the east side of the Xuan, there is a guqin-shaped moire stone, which is 1.64 meters long and nearly 1 meters wide, and inscribed with "Hengqin".
