Introduction to the Octagonal Pavilion: The Octagonal Pavilion is part of the entire building group of Guiyun Village. It was built by Lu Chengfeng, a hero of Taihu Lake, imitating the architectural structure of Huang Yaoshi's Bagua Hall for the young master of the village, Lu Guanying, to practice martial arts. In the structural construction of this pavilion, the mysteries of the Eight Diagrams are contained, which is infinitely profound.
