Zhenwu Pavilion, located in Rongxian County, Yulin City, Guangxi Province, is a key unit for the protection of cultural relics throughout the country. The Pavilion is a leveraged pure wood structure with a height of 13.2 meters, a width of 13.8 meters, and a depth of 11.2 meters. The Pavilion does not need an ironware. It uses nearly 3000 latticed wood components to support each other, restrict each other and reasonably coordinate to form a beautiful and stable unified whole. The most amazing thing is that the four pillars of the second floor are hanging without touching the ground. It can be called the world's ancient architectural miracle and has high scientific research and artistic appreciation value.
