Introduction to Tiantan Pavilion: The total area is more than 1,000 square meters, the total height is more than 30 meters, with a total of six floors, two underground floors, and four above ground floors. It is an adobe and stone structure imitating the Thai and Han Dynasty concrete. The south wall is 19.99 meters away from the Nantian Gate. It has two meanings here. One is that it was built in 1999; the other is that Taoism talks about odd numbers, and the other means that it will last forever.
